All I'll say regarding ReStore is that like any other store , they are there to make money , not cater to collectors . Plus , you also need to factor what they pay to rent the space they're in . The building we moved into in 2005 cost us $3.76 per square foot per month back then !!
Then add in insurance , employee saleries and it adds up quickly . They need to stock popular stuff that'll sell quickly , not niche stuff that'll sit for awhile and take up valuable floor space . Also , if they accept cases of fluorescent tubes for example (hazardous waste) the cost to disposes of them if no one buys them just destroys any profit margins !
All in all , I don't go into ReStore expecting to find rare items but it DOES occasionally happen and I do occasionally find some really good deals and cool items !
Maybe someday I'll find that case of caution yellow Lifeguards !! (HIGHLY DOUBT IT !!)
