Yeah, that seller is on crack asking that much

One was a repacks offering that seemed at a good price, he suggested he had a list of the cards. Looking at the list buying all repacks seemed a good deal and I just made an offer for all and he threw in his spare (un)commons and some other stuff.

On another occasion there was a way overpriced collection (300 euro for 3000 cards), but with a few random, but very good looking legends cards in the photographs. Asked him for more pictures explaining that what he was showing didn't really come close to justifying the 300 euro. First a picture of an Island of Wak-Wak came in, later pictures included some cards an old school player would have really enjoyed (like Glasses of Urza) and finally, surrounded by a lot of crap and a Legends Vaevictis Asmadi: a Mox Emerald. Offered 250 assuming the Mox would be fairly damaged, which he accepted, turned out the Mox was NM and the collection included a lot of other old goodies not visible in the pictures and almost everything was in EX+ – NM+ condition (Mana Drain, a whole stack of Chain Lightnings, Mirror Universe, many Legends from Legends, Duals, Factories, etc.).

For a fellow student at the university I agreed to appraise his collection. Lots of Beta stuff and a lot of cards from then till Ice Age. Told him all I could offer was 400 as I just didn't have more, 600 could easily be had selling on marktplaats and probably 800 with a little effort. He was ok with the 400. I moved most of the Beta stuff a week later for 350, leaving me with plenty of other goodies.

What I am saying is, let the other guys snipe the collections that are obvious and make a little money on it. Wait for the good ones yourself and of course, when an opportunity arises among the people you know, jump on it!

I should add that I also don't have time to move a lot of small collections, so time wise going after the weird but high profit ones is more logical.
