The way I feel if your in it for the money you need to go online. If your in it for the experience and meeting people within your hobby then open a store, but don't expect much of a monetary return if any for your time and effort. With a store you are either going to have to set a lower profit margin or use it as a front to sell the games that aren't worth putting online while accumulating inventory from people looking to sell there stuff. Really that's about the only upside I see to a physical location is people tend to flock there to resell there stuff. Although a lot of those people are a hassle to deal with since many bring in beat up stuff expecting to sell it for a lot more then it's worth, and when explaining the market to them most people get offended
.
There is also taking into effect the negative impact that sites like VGPC have on the hobby since while nice tools they are horrible for determining offline prices given they don't factor in shipping costs and market/payment fees. For example an average cased disc based game from this generation is going to cost you at minimum $2.60 to ship then you have to factor in the fees which are going to be 12.9% and $0.30 for an average ebay seller using paypal. So suddenly that game that has a average price of $10 for a CIB copy on VGPC is only worth $5.80 in reality, but coming to that realization would require some actual business sense which the average reseller seems to be lacking
. The funniest thing is it's a never ending cycle of resellers around here because it seems like every time one goes down they sell their entire inventory to a single person who then proceeds to make the same mistakes they did.
If you want to know what inevitably kills a collector's market and causes prices to sky rocket it's tools such as guides and price charts that try to nail down a monetary value on every individual item. If people have a tool telling them something is worth X amount of dollars they will stick to it whether it is right or wrong
