shipping by weight with PayPal query
I've been looking for a solution for calculating shipping by weight as used in PayPal. Trends are that a base price (min. shipping price) along with additional fees (calculated by the lb) is most accurate. For example a minimum shipping of $3.99 plus $0.50 per lb.
I don't see any solution for this, though as thorough as this app is, I'm sure it can deal with this. I was thinking of:
(1) adding a shipping weight column though I'm leery of altering anything without the good word.
(2) creating a custom cart (since weight is not built in the database) and plugging in values manually - again I'd like to know what the word is on adding columns since manually is error prone and the long way round.
(3) if I could add a weight column, how would I call the value and have it inserted into the cart's post functions during publishing.
Ideally, a minimum shipping price (prior to any cart item submission) with an additional cost per lb for each item purchased is the goal.
PayPal's calculator work three ways: by # of items, by cost, and by weight (which is the only one which makes sense for me...
So not having weight in the database or post is my dilema. Any recommended suggestions?
