eBay tracks the number of one-star and two-star DSR ratings that a seller receives. A seller is allowed no more than two low DSR ratings within each reporting period and the percentage of low DSRs cannot exceed 0.50%. I've done pretty well being back on eBay since June, but I knew that I would eventually run into DSR problems again. An eBay buyer has left me a low shipping cost DSR for a recent order.
Without getting into the specifics due to certain eBay policies, I was able to figure out beyond any doubt which buyer left the low DSR. A certain buyer purchased two books in one order. I received three stars for the first book and two stars for the second book purchased by that buyer. I guess the buyer thought that the postage of $3.95 for the first book and $0.60 for the second book was too high and deserving of two stars for one of the books.
I was not surprised that this particular transaction was for inexpensive books. Many sellers report that the most troublesome buyers are often the ones who purchase cheap items. Since the postage cost was as high as or higher than the item cost, the buyer must have felt that I charged too much.
Since I now have one low DSR rating on my account, I am in a precarious position. If I receive one more low rating on the shipping DSR, I will fall below what eBay considers acceptable. In order to protect myself, I have changed all of my listings over to free shipping. With free shipping, I automatically receive five stars for shipping cost, which means that no future buyer can leave a low DSR in that category.
I figured out what I paid for postage and packaging on the transaction that resulted in the low DSR, and I broke even on postage. I did not overcharge at all. I have now blocked the buyer who left the low DSR in order to prevent that person from making additional purchases and leaving low ratings.
The buyer knew the postage cost before completing the order. If the amount seemed acceptable before completing the purchase, then the buyer should not have left a low DSR. I have seen listings where I consider the postage to be too high. If the postage amount takes the total cost above what I am willing to pay, I do not purchase the item. If the postage amount keeps the total cost within what I am willing to pay and I decide to purchase the item, I do not ding the seller's shipping cost DSR. I made the decision to purchase the item, so I take the responsibility.
