Just posted the updated files to the following WePay Plugins:
WePay Checkout 2.2 OsCommerce
WePay Tokenized Checkout 1.1 Oscommerce
WePay Checkout 2.2 Zen Cart
All plugins have received the latest version of the WePay PHP SDK. The code was also slightly cleaned up in the WePay Checkout 2.2 Plugin for OsCommerce.
No huge charges, the biggest thing was charging taxes on the checkout. You can now do that but you have to set the tax rates in your account from WePay.com
Let me know if you have questions.
I use this alot so for people in need here you go. I generally need it for oscommerce stores for updating products price based on a percentage on the fly. When there are 1,000 or more products this is the best way to update them all.
update products set products_price = products_price + (products_price * .35)
