its funny you mention this. I actually had heartsy voucher people PAYING through paypal. I think at least 4 people did it, which shocked me.
But I also did have a few people come through and use the "other" option out of confusion. One of the orders I cancelled, because I want to be consistent and stick with my "policies" and she did come back and re-do her order once she figured out paypal.
I was excited to shut off "other" when my deal expired, and I wouldn't have even remembered if I hadn't seen your post, so thank you!!!
