Setting minimum charge for USPS Shipping

[mystic-journey]

Hello,

I've been trying to figure out how to set a minimum charge for my USPS shipping. I do not want to add a handling fee on because obviously this will be added to all orders. Since my dropshipper does a $8.00 minimum shipping amount, i would also like to have this. Could someone please explain to me how and where I can do this?

Thank you so much in advance!

What about doing zone rates? I don't know what you sell to see if this is feasible or not for your situation?

What shipping methods on USPS are you using?

Are you wanting this Minimum Charge on *all* methods that are not already >= $8.00 for everyone regardless of US or International?

I don't know too much about zone rates and I would like this to be on all shipping methods but I am most concerned about the USPS method since that is what I am currently using. Thank you so much!!!

You could edit the module:
/includes/modules/shipping/usps.php

by adding the code in RED:

// switch comment marks to show $hiddenCost: from quote title
$show_hiddenCost =  ' $hiddenCost: ' . $hiddenCost;
//$show_hiddenCost = '';

// bof: force minimum of $8.00
if ($cost < 8.00) {
  $cost = 8.00;
}
// eof: force minimum of $8.00

          $methods[] = array('id' => $type_rebuilt,
                             'title' => $title . $show_hiddenCost,
                             'cost' => $cost,
                             'insurance' => $usps_insurance_charge,
                            );

Ajeh is asking that when shipping anything/everything via USPS regardless of size, destination, speed, etc. That if USPS is being used do you want the minimum charge to be $8.00?

[mystic-journey]

Yes, that is exactly what I want. The minimum charge to be $8.00. Thank you.

You are most welcome ... glad to have been able to help!

Thank you so much!! This worked:) BTW... I asked for a quote from someone to do this for me and was quoted $80/hr and it would take 2 hours. I can't tell you how thrilled I am that I pushed ahead and asked questions.

BTW, though I hadn't seen that Ajeh had provided the solution (was reading emails from the thread rather than the thread itself) I had come up with something a little less "intrusive" though haven't tested it, just a "thought" experiment, but was something I was thinking could work for others in the future... Involves creating 2 files and using the observer/notifier systems. To be ever more elaborate could add some configuration items into the USPS script for install/remove to provide a field on the admin panel to replace the hard coded 8.00 that is below. Was written with consideration of the "standard" update function possibly going away (I doubt) so yes the same code is listed twice, but with the redesign in ZC 1.5.3, there are a few more "options".
