I was on a shopping mood the other night this really put a damp on my spirits, was about click BIN to buy a Chanel bag from very good seller when this happened during another (earlier)transaction. This is for both buyers and sellers who use channeladvisor checkout in combo with Paypal. There appears to be a bug with checkout and you need to be aware of this problem! I have already reported the problem to both since this happened late Sunday eve and have yet to receive a response back. Basically this is what happened. Over the weekend I won two items from an eBay seller who does checkout via channel advisor. Done this before many times without a problem ever - at least several dozen transactions before this one. When you use channel advisor checkout it summarizes your order, allowing you to combine items to save on shipping. Buyers also select the address to ship to (in my case I have two addresses to choose from, both correct, verified and confirmed) and all of that is fine up to the point you reach Paypal to send payment. So I moved thru the steps, selected "pay by Paypal" which tranfered me to the Paypal website. This is where the problem comes up. I am reviewing the order making sure the information is correct: amount to pay, who's receiving the money, my info, address to ship to, etc. I notice that my address is wrong, even though I had picked the correct address from the two I have during the previous steps (both eBay and the channeladvisor checkout steps). OK so no problem, I notice that and it should not be a big deal to select the one I want to use. I clicked to select the address from the DROP DOWN menu. WELLL.... at the point where it is SUPPPOSED TO choose one address vs the other, it does not do that. Instead this sent the payment right away from the checking account not allowing me to correct the address, nor confirm the payment, nor change the funding source. Basically by clicking on the drop down menu it sent the money from my bank account without confirming anything and sent the order to the seller with the incorrect mailing address. Neither the items nor the amount for me were an issue ($360.00 for home bedding) for me. But what IF I wanted to make sure I used a credit card to protect this transaction, which by the way, I 100% do all the time just to have a little extra coverage? I never had that option because by me clicking on something else on the page this action alone sent the money directly out of my checking account when all I was trying to do was choose the correct address! What if I was at my vacation home and not my house (both addy are confimed, so the seller is protected but I would not get the item cause nobody is home)? What if I had needed the money in the bank for other payments or had pending checks? I can assure you many people must have had this problem over the weekend and you as a seller may be getting notices now that some of these payments are being reversed, denied or cancelled from the banking institution. Still wanting the Chanel bag, but not buying anything until I hear back that this was corrected!
