Multiple Merchants
I'd like to add a express PayPal option to an existing AuthNet eCart implementation but don't quite know how 2 merchant WA_eCarts might work together on the site. If I create a separate cart for PayPal then how would the both WA_eCarts know what's customer has purchased at checkout should the customer decide to use the PayPal option? It seems like I would have to create 2 separate stores for each option which is of course ridiculous for a site with hundreds of products.
