Our customer who desired this seems under the impression that the user can complete a transaction, paying with Paypal, but never leaves the OSC part of the site (controlling the look/feel is of paramount importance). However, from what I am reading here it seems that it is mandatory for the user to be sent to the Paypal site to complete the transaction. I realize that once there, the site can be partly skinned using a custom Paypal page, but the skinning options are limited.
Can someone confirm or clairfy my understanding so I can advise my customer accordingly? Any help is most appreciated.
