I didn’t even know you could sell stamps on amazon. Wow

Looks like a policy change. There doesn’t need to be a “why” just a “this is what is happening now”

Probably because everyone is selling them for more than they are worth. Why would you spend $.68 to $.82 a stamp when the Post Office will mail them to you for $.50 a stamp.

Maybe they made a deal with the post office to only allow USPS to sell modern stamps. The post office can therefore eliminate their competition easily this way.

A few months back, many listings for US postage stamps were removed.

There are multiple threads on this forum,

No explanation was provided then.

 Stu...we have to stop meeting like this.  (This is the second time!) 
 There has been an ongoing problem with Counterfeiting for a long time, and sellers like us - by which I mean ASDA Members/Professional Dealers - are getting caught up in it.... first, when the non-pros are buying fakes and seriously undercutting our prices...and second, when Amazon sees enough complaints to prod them to action.  
 You and I went thru this last Spring.  Counterfeiting is still a "major crime", and Amazon is willing to throw out us babies with the bathwater to protect their customers and to keep their image clean.
 I can't say I blame them, much as it hurts.  Perhaps we can work thru the ASDA to develop a relationship between the ASDA and Amazon which recognizes the safety of dealing with professional Stamp Dealers and allows us to enjoy the benefits of the Amazon platform.

maybe because the USPS sells them at costco now, and costco likes to have exclusives? most likely the USPS told amazon to stop, but it’s irrelevant.

It would be very easy for Amazon to block the sellers who sell fakes if they made an effort at it. It is a shame their solution is to just end the sales of everything instead of actually taking the time to ban the offending users.

There were quite a few reputable sellers offering collectible/out-of-print stamps for either collecting reasons or for invitations etc. that the post office has not sold for years. Even if Amazon does start selling stamps themselves they will not be able to offer these products.

It’s what they should have done but they throw people off and they just come on back.

Not hard to understand. These stamps are too easy to fake.
