Per Weight Unit Shipping

I'm using this module and when I go to the checkout and select a quantity of 13 units at 25 lbs each the total per weight unit shipping cost is 13*25= $325. The per weight unit shipping says the formula that is used is Product Quantity * Units (products_weight) * Cost per Unit. Am I doing something wrong? I have the tare weight set at 0 and max units at 5000. Thanks, :wacko:Charles

The Per Unit perweightunit shipping module is designed to take the Total Weight and multiply that by the Rate ...

If you set the Product Weight to 1 and buy 10 and the Per Unit Rate is 1 the charge is:
1 * 10 * 1 = $10.00

If you set the Product Weight to 1.25 and buy 10 and the Per Unit Rate is 1 the charge is:
1.25 * 10 * 1 = $12.50

If you set the Product Weight to 1 and buy 10 and the Per Unit Rate is 2 the charge is:
1 * 10 * 2 = $20.00

If you set the Product Weight to 25 and buy 13 and the Per Unit Rate is 1 the charge is:
13 * 25 * 1 = $325.00

What are you "meaning" the charge to be for this Product?

Thanks for the answer, I understand how it works now. To answer your questions, for each product weight there is a different value (ie: product a = 15lbs whereas product b = 25lbs.) The actual weight I stated in previous email (25lbs) is the weight of 50 rolls of paper cash register receipts inside a shipping box minus the tare weight. Speaking of the tare weight, I read in a previous post that it is not necessary or a factor for shipping by unit? Charles

You want to set the Tare Rates to 0:0 as they are used in a calculation to add weight and you do not want the weight adjusted in any manner ...

The Maximum Weight 5000 is so that the Total Weight is not adjusted in any manner, either ...

My apologies if I've put this question in the wrong place...did a search for "prevent ups rates from displaying during checkout when perweightunit is used" and got no results.

I use freeshipper (zero weight), ups, and perweightunit (flat rate) for shipping on my website.

How do I prevent the ups rates from showing up during checkout when the flat rate shipping applies to the product?

It senseless to display the outrageous UPS rates on a product when the flat rate price is so much cheaper.

You have me a tad confused here ...

You say you want to use:
FREE SHIPPING! freeshipper
UPS ups
Per Unit perweightunit

But then you reference:
perweightunit (flat rate)

Where does the Flat Rate flat come into play here?

When you want to disable the UPS shipping module and use Per Unit perweightunit ... how do you use UPS and Per Unit perweightunit in combination with one another?

You also have Maximum Weight at 5000 ... this means that when Shipping Weight exceeds 70lbs for UPS that UPS will not be able to provide quotes ...

So I am a tad befuddled here ... could you perhaps type really really slow and explain what you are trying to do with your shipping? :lookaroun

I have a few thousand of products that have different flat rate shipping rates, several thousands products with free shipping (zero weight), and many thousands of products with UPS rates...

I have been using freeshipper and UPS successfully for almost a year. In the past, I added shipping cost back into the base price and sale price with my php scripts which enabled me to handled flat rate shipping products as "free shipping" products. Some people may not appreciate that...semantics. So I'm trying to reflect exactly how the shipping prices are handled via my supplier.

I am trying to add perweightunit to handle my products that have flat rate shipping.

When I enabled perweightunit shipping, it caused the UPS shipping price to show up with an outrageously high shipping price on products that have flat rate shipping (because the shipping price is inserted in the weight slot). I need to stop UPS prices from displaying during checkout on products that have flat rate shipping.

On products that do not have flat rate shipping (I.E. UPS rates), the flat rate shipping shows up as an option during checkout as a lower amount than the UPS rates. I do not want flat rate to display on products tagged as UPS shipping.

There are no issues with free shipping...

I hope I've made it clearer than muddy water this time...LOL.

Appreciate your help.

What would be a could indicator in the table:
products

to distinguish which Products uses UPS and which Products use Per Unit perweightunit?

Do you have a field for this? Or can master_categories_id be used for this?

I don't see any "could" indicators in the zen_products table.

The initial table (my_products_dsdi) I import my products and updates in to has columns call "SHIP_METHOD" and "SHIP_PRICE".

SHIP_METHOD can be Individual Shipping, UPS RATES, or Free Shipping

SHIP_PRICE can be 0 - whatever

I'm not sure what you are implying by "can the master_categories_id be used for this".

Thanks.

I see where the confusion may be coming in. I ran across a method of using perweightunit to handle different flat rate shipping charges on Picaflor-Azuls website.

The native Flat Rate shipping module in Zen Cart isn't flexible enough to handle many different rates (without modification) so I was looking for alternatives.

Within perweightunit, setting the shipping cost per unit to 1 and putting the shipping cost into the weight field does enable me to have many different flat rate shipping rates...but it also screws up the UPS module.

So, I hope that clarifies the confusion.
