I didn't come across any steals really, just retail-ish or what you'd expect to pay with shipping. The only benefit is you get to see/handle the item first which is certainly a bonus.
For my BBTS Seacons I paid the same as what it would have been sent to my door, but I had been on the fence about these guys so wanted to see them in person. Once seen, I bought them.
For my C310 Reissue MIB God Ginrai I paid $100, might have overpaid, but the 2 other TRU versions (inferior version) that were on the dealer floor were $150+. So I am quite content paying what I did.
I think my Encore Ratchet/Ironhide +Heads (heads were only included if you bought both) were the closest to a deal I found. The dealer wanted $60 for the bundle. I was down to my last $55 so I offered that and he accepted. Nice guy, he didn't have to throw in the heads seeing as I came in under his price.
As for Universe Cosmos, he was a 1:1 trade. Best kind of trade
My goals were to get PM Prime/Godmaster God Ginrai and Encore Bruticus, I only saw one Encore Bruticus and they wanted $200. For that I'll just get a vintage one for less :P
