Just surfing
ebay early this morning looking at various year sets of the 90's. Finding most of them being more than I want to spend, I came across this BIN listing that the seller had on sale at 50% off his normal price. Obviously a seller that doesn't deal with stamps.
http://www.ebay.com/itm/22113309951....m1439.l2649USPS yearbook sets - 92, 93, 94, 95, 97, 98, and 99. All but 2 still sealed
+ 5 of those commemorating the decades sheets - 1900s through 1950s
everything for $102 delivered. I would think face value alone on the stamps would far exceed that price.
Love it that those sets come with all the various sized mounts too.
