In regards to a seller (store) wanting to set a combination of an item discounted (ex: 15% off sale) AND a promotion (ex: Buy $30, save $5), there is a major problem that affects both buyer and seller.
Apparently, even if the seller has "NOT" checked immediate payment due on any of their listings, eBay has implemented an immediate payment due on items that have been placed on "sale."
By eBay forcing immediate payment per item on a buyer, it prevents the buyer from purchasing multiple items as they forced to stop and checkout and pay for each item individually.
Bottom line is that due to eBay forcing the buyer to pay immediately when an item is on sale, the "promotion" that a seller set up to bring buyers to their store in hopes of purchasing more items ends up being negated.
This issue was just discovered this weekend when a buyer took the time to detail their frustration with this issue and stated that it is a repetitive problem when trying to purchase multiple items from a seller offering both discount and promotion. They blamed eBay!
I know this doesn't make sense but it is truly happening. In fact if a seller has multiple stores they can check it out for themselves buy setting up a sale on their items as well as a promotion. Then go into one store to buy in your other store. Yes, you can put something in your cart but when you proceed to request an invoice from seller, you (as the buyer) will get a message, "Because the seller is offering discounts on the items, you cannot request a total." Thus, the buyer is forced to pay for each item individually.
As any seller knows when a buyer pays for items individually, new problems arise. First, you must know how to combine the items (NOT thru sales record) and be prepared to immediately ship the items (packaged, know the weight, etc) when doing so as the system will want you to proceed to print the label.
And forget building in a little extra for shipping as eBay does not allow you to hide the postage; thus the buyer knows exactly what it cost to mail compared to what they paid. I often allow for the cost of the box, packing material and a portion of the fees when setting my shipping cost but at least I have an option in the regular eBay shipping label or stamps.com to choose to "hide the postage." Can't hide the shipping when combining items that were paid for individually in eBay.
But the real problem here is that a buyer is prevented from purchasing multiple items in one transaction in order to take advantage of both promotions, the discount on the item and the bonus discount for purchasing multiple items (other promotion options are available but the example of "Buy $30, save $5" is the type of promotion I know of right now to have this problem. Other promotions may be affected too.)
End result, is unnecessary frustration for both buyer and seller and unnecessary time adjusting shipping, refunding $ for the "promotion" etc.
If this has not been covered, please put this out there for other seller's experiences and feedback. It's bad business for eBay to require immediate payment when the seller has not. It's one more way of eBay making it difficult for both buyer and seller to complete the transaction and is utterly and completely senseless. (I know, what else is new?)
eBay please wake up and fix this problem!!!
