I can tell you several things about
ebay sellers in general. There are sometimes legitimate reasons for not allowing sufficient time for expertization, one is that the material could be on consignment and the seller needs (or wants) to settle quickly with the consigner. But I do not consider this (or any) reason that a seller won't allow sufficient time for expertizing to be acceptable ethically. To me, ANY product that is sold should be guaranteed to be 1. genuine and 2. "As described". If no faults are disclosed, then a buyer has the right to expect a 100% sound stamp.
This is a HUGE subject and I don't have a whole lot of time, but here are several more points to consider. There are a number of
ebay sellers who won't allow adequate time for expertizing. Even though some of them are basically honest overall, I still consider them at minimum to be ethically-challenged if they won't. But there are several ways to BEAT their restrictions;
1. My expert services include an express service which is guaranteed for 3 days from day of receipt. That costs only $5. in addition to the regular fees (see
www.stampexpertizing.com for fees). This service allows buyers PLENTY of time to meet the time restrictions imposed by these sellers;
2. Find out if the seller is an APS member. If so, he *MUST* abide by the Bylaws and Code of Ethics. This means that if you buy a stamp from him and it is repaired or altered, he MUST take it back, even if the time limit for returns has passed.
It happens that the seller of that stamp *IS* an APS member. His name is J. Sun. That seller lists a lot of stamps (US) that have undisclosed faults. I advise anyone buying from such sellers to be very careful. This stamp (the #460), for example, appears to me to be reperfed at bottom, and possibly elsewhere. You made a great decision not to bid. I have reported it to try to stop the sale. I may or may not be successful, because this seller is one of those given special status by
www.ebay.com/b/260/" rel="nofollow">ebay, being big enough that he has his own Account Manager, who insulates him from the usual procedures followed by
www.ebay.com/b/260/" rel="nofollow">ebay for removing fraudulent stamps from their site. It is therefore difficult to get corrective action against his listings, which is even another reason to be cautious -
www.ebay.com/b/260/" rel="nofollow">ebay coddles him and other BIG sellers.
Last, the best advice I can offer anyone buying from ANY seller is to avail themselves of professional expert advice and services if they are spending decent amounts of money for their stamps. Also always ASK a seller what his policy is BEFORE you enter bids on his material. If he does NOT allow expertizing, my advice is to forget about doing business with him, as stated earlier, there is NO reason that is acceptable enough to deny a buyer the right to get the material expertized. If they have TOUGH restricted limits on the days you can return misdescribed items, then either use my express services or forget buying from such sellers too. There are LOTS of honest dealers out there. Seek them out and patronize them and forget about the ethically-challenged ones.......
