I wonder...
What the stamp market actually looks like today for most collectors?
What percentage of the stamp collecting buyer market has transitioned to online platforms such as
ebay?
What is the current role of the traditional stamp dealer?
And how important are dealers who direct mail their inventory buy lists to targeted collectors?
Since 2010, I have been seriously building my collection of US Classics. Starting first with affordable albums I have moved from classics, to include 1940's through 1970's, and expanded into BOB and Revenues. Relying on
ebay auctions and making best offers I have purchased numerous albums and lots as the foundation of my collection. Now I'm purchasing older single stamps in order to fill gas.
Honestly, as much as I would like to support stamp dealers -- most of whom are very small owner run businesses -- dealer pricing makes it very difficult to do so.

Recently I purchased 20 single stamp lots of higher value used US stamps from numerous
ebay dealers. In each case I compared my
ebay purchase price with a dealer list price for the same Scott US cat # and condition. Here are a few examples from my comparison:
US #36 SCV $350 Dealer List: $89 My
ebay cost: $12
US #122 SCV $2100 Dealer List: $1000 My
ebay cost: $400
US #292 SCV $700 Dealer List: $525 My
ebay cost: $230
My conclusion: With apologies to dedicated dealers, my budget can't afford regular buying from dealers. Except in rare cases I'm sticking with online auctions and making best offers.
What are your preferred sources for building your own collections?
