Quantity Discounts for 1.3

[CharInLasVegas]

There's a bug in your syntax. Instead of

        switch($category) {
           case 14:
15:
16:
17:
etc.

you want

        switch($category) {
           case 14:
case 15:
case 16:
case 17:
etc.

OH, ok thanks!!!

hi, i have quantity discount installed, but i met the problem when checkout

- i check out 2 items (price 20 + 30), total shipping cost 15.90, quantity discount 5%, tax 19.6%,
- i set the price with tax, and shipping cost no tax.
- i set the sort order which i want in module:
sub-total -- 200
shipping cost -- 210
quantity discount -- 220
taxes -- 230
total -- 240

----------------------------------------
which i should get is :

sub-total: 50.00
shipping cost: 15.90
quantity discount: -2.50
tax: 7.78
total: 63.40 [ total = 50+15.9-2.5 = 63.40 ]

----------------------------------------
But, no matter how i set up, its not what i want:

i set quantity discount: include tax - true, re-calculate tax - standard, i get

sub-total: 50.00
shipping cost: 15.90
quantity discount: -2.50 [ 2 items 41.81*0.05=2.09 (include tax = 2.50) ]
tax: 7.70
total: 62.91
----------------------------------------
i set quantity discount: include tax - true, re-calculate tax - none, i get

sub-total: 50.00
shipping cost: 15.90
quantity discount: -2.50 [ 2 items 41.81*0.05=2.09 (include tax = 2.50) ]
tax: 8.19
total: 63.40
----------------------------------------
i set quantity discount: include tax - false, re-calculate tax - none, i get

sub-total: 50.00
shipping cost: 15.90
quantity discount: -2.09 [ 2 items 41.81*0.05=2.09 ]
tax: 8.19
total: 63.81
----------------------------------------
i set quantity discount: include tax - false, re-calculate tax - standard, i get

sub-total: 50.00
shipping cost: 15.90
quantity discount: -2.09 [ 2 items 41.81*0.05=2.09 ]
tax: 7.78
total: 63.40
----------------------------------------

if i add more items, the amount would be more outrageous

when i turn off quantity discount, everything calculates correctly.

i'm using 1.38a

how do i fix the problem ? i like this module very much, i dont want to loos it. thanks

It seems the setting you wish is not available. You are welcome to modify the code or to hire someone to do it for you.

hello,

here's my invoice with quantity discounts on

sub-total: 50.00
shipping cost: 15.90
quantity discounts: -2.50
tax: 7.70
total: 62.91

the total calculation is not correct

total = sub total + shipping cost - quantity dissounts
= 50+15.9-2.5 =63.4

but i have no idea why 62.91

[myworld20091]

what i want is using quantity discounts, and calculation correct

[myworld20091]

i do not have any special requirements, i just want the quantity discounts working on my zencart 1.38, but now the calculation is not correct
any help would be appreciated

hi swguy,

they are not the settings i wish but the settings i have tried, i have tried perhaps all settings cause the calculation is not correct in the invoice, i dont know which setting is correct, thats why i posted them here.

i do not have any special requirements, i just want the quantity discounts working on my zencart 1.38, but now the calculation is not correct.

here's my invoice when i turn quantity discounts on

sub-total: 50.00
shipping cost: 15.90
quantity discounts: -2.50
tax: 7.70
total: 62.91

according to the invoice, it should be :
total = sub total + shipping cost - quantity dissounts
= 50 + 15.9 - 2.5
= 63.4

but now the total is 62.91, its obviously wrong, but i have no idea how to fix this problem.

could you help me? thanks.

I Installed this mod and the preview feature in 1.3.8a. Works fine in every test I run. Today had a user checkout using paypal express checkout bypassing the checkout on my site. Discount was not applied. I assume this is because even though the preview can show the discount in the cart, it does not pass this discount to express checkout? Is there a way to apply the discount to users who choose the paypal express checkout method from the cart page?

[swguy]

I have not heard of this problem. Does it happen on every express checkout? Are you certain the user qualified for a discount with the items they had? Can you reproduce the problem?
