Well I have run into my first issue with Auctiva. When you have a buyer for multiple items, and you have AUCTIVA checkout enabled, you cannot combine invoices on ebay.
This is a issue for me as I often run into multiple item buyers for my auctions. In this case I launched about 100 auctions and several multiple auctions buyers either paid for each item seperately via Paypal, or are mailing a check because they don't want to go through checkout 8 times.
so, the extra Paypal fees cost me money, logging into Paypal to do the invoice costs time, and mailing payments now means I have to manage these acutions manually.
NOT GOOD.
SO I HAVE TURNED OFF AUCTIVA CHECKOUT. I lose the shipping kickback, but it's not worth the hassle to use auctiva checkout.
