I have had purchasers abort the purchase after completing the signup page. When they come back to make the purchase they can't get past signup because they get a duplicate username error. Some send me an email - I don't know how many give up and don't come back. This is a serious problem because I have to delete the amember record so they can complete an order. I suggest collecting username/password on the 1SC page, and passing it to amember along with purchase info after the purchase is complete. 1SC identifies amember products so this should be an easy mod - eliminates having to send 2 messages to amember, and eliminates problem for users that don't complete a purchase 1st time through, and then come back and get stuck in the process.
Is there a work-around for the problem I mentioned above? Can you have the aMember signup page follow the checkout? If not, how can a purchaser get past the duplicate username problem when coming back to complete the purchase?
