Hmmm... the numbers are fact, you just have to keep an eye out to notice the overall declining DSRs eBay wide. It's not like eBay is going to advertise that DSRs are falling noticeably across the board.
The numbers for DSR calculation are basic math, verification doesn't enter the picture. By your own admission, 4.8 is a superior DSR and if your sales are what you stated, then please correct any miscalculation I forgot to take into consideration, baring in mind my extrapolation is approximate as I am not privy to your actual sales summary's.
My intention is not to put you down Pierre, you just happened to state real numbers for your experience. While the performance of any specific vendor in any specific market is determined by the market and their practices, that is a totally separate issue and probably warrants a wholesome discussion in another thread, but that will probably lead to an ethics debate.
Perhaps you missed my conclusion of the whole eBay experience, where I said I would be adopting your business model and stay within my small niche market. Philately (sp?) is the number one hobby in the world and less prone to the seasonality of my niche market which means I am unlikely to qualify as a power seller 12 months of the year.
I have spent 6 months experimenting with eBay business models to determine the best approach and if it's all worth it or not. As a very small niche vendor, it is borderline and ANY loss of funds tips the scales against me so I have to run a very tight ship or go down with it ;p. It's not my goal in life to invent ways to sell product on eBay that most benefit eBay.
Oddly enough, eBay was born to service people exactly like me, but now we are just baggage to be tossed around on the loading dock because eBay can't survive unless they suck vendors into taking on more than they really want to buy dangling carrots over the precipice. eBay was never intended to be a competition among sellers, the original goal was to provide a platform for all the little people to have access to the internet for selling their stuph.... but nothing is static, so here we are, full circle, back where we were before eBay was launched.
Like so many other good ideas, eBay is now a perfect example of what it was created to battle against.
So now, the issue was... are the FVF credits a flop or not... I guess that pretty much depends on what your expectations were and which side of the fence you are on. First, lets get right down to it, FVF Credits are an incentive program. Incentive programs are designed to increase sales/income, they are not there because eBay loves you.
From the program sponsor's point of view, FVF Credits are a success if they convince you to increase your sales and result in an increase in FVF, which is the sponsor's profit margin and goes right to the bottom line, while insertion fees are designed to cover the operating costs. Only the sponsor knows if a program is a success or not and they may quantify that by setting specific targets for FVF increases. If FVFs go down, it's not likely related to the incentive program but is probably entirely attributable to current economic conditions, so additional metrics need to be applied which typically would be looking at individual vendors or specific categories. One can massage the numbers to suite them, but the best metric to measure incentive programs is to look at the individual vendor's pattern.
From the sellers point of view, an incentive program is successful if it results in an increase to the vendor's bottom line. How much that increase is in real terms or percentages only quantifies how beneficial the program is. Or in other words, if you get ANY rebate, it is benefiting you. IF you have to incur higher expenses either in real or intangible terms, then it becomes a subjective determination, but if the incentive program is luring you into doing things you would have otherwise not done, then you really need to step back and do a risk/reward analysis. Incentive programs are primarily designed to benefit the sponsor, so the requirements, incentives and qualification levels have been carefully modelled against years of data to determine what those numbers should be to produce the maximum benefit to the sponsor. From a vendor's perspective, the real issue is not whether the program is successful, but rather is that program meeting the vendor's expectations. The answer quite simply is usually no, because that is not the purpose of an incentive program. It's a lot like the lottery, your expectations are high, you don't buy lottery tickets because you really want to win $10.oo, so one tends to view the experience more negatively each time those expectations are not fulfilled.
Bottom Line.... I get a 5% rebate each month, that's $2.12. If the world was just about to end and I got 15%, that's just enough to buy a medium double double and a crullers for two people. Obviously that is not enough to expend time or energy on, or to increase my risk level by chasing the 15%. But I'll gladly take the free coffee each month because being on a disability pension, a dollar is a significant amount of money.
