This isn't offered as something to duplicate exactly, it's more some food for thought and a general approach that might work out for you and I'm not going to be over-specific as I'm still watching for opportunities and maintaining the relationships that made it work. I went to some pawnshops some time ago looking at guitars, mainly for a cheap but decent full-size acoustic and crossing my fingers for a variax. At one of the shops I went to they had 5 identical acoustics that are widely regarded as one of the best full-size student guitars for the money. They were all in equally excellent shape and correctly set up. I negotiated the price down and bought one. The negotiation was recorded on a onesheet that had the brand, model, serial number and a color picture of the guitar that the saleman had printed. When we agreed on a price, he took the sheet to his manager for her to initial. I walked out with the sheet, receipt, and the guitar. When I got home I looked what I had bought up on ebay, found they were a fairly hot item at the right price and estimated I could get about double what I paid plus shipping without much trouble - smart beginner guitar buyers like when they're already set up, because when you buy an axe online if you don't have basic luthiery skils you'll often spend $50+ having it strung and setup so the action will be right and it'll take and hold a tuning, like a playability tax. Anyway I scanned the picture, posted the auction at what I paid with no reserve, and it closed for about what I guessed it would. I bought another of the same guitar for the same price at the pawn shop, walked it next door to the UPS store where I netted out positive for a cardboard coffin, packing and insured ground shipping. The part that excited me was how pure the arbitrage was. I just posted a picture, got paid via paypal, used my paypal debit card to pay for the thing, and shipped it to my customer from the same shopping plaza, and pocketed profits with no direct outlay and about 30 minutes of effort. I have other business interests and prefer web development to spending time in pawnshops but it was very interesting and entertaining to take advantage of an impedance mismatch between a local market and an online market. I'm sure there's lots of opportunities similar to what I found if you're familiar with certain products and good at negotiation.
