There was a small computer and electronics retailer on Oahu called ByteWare that had better/more computer inventory than the larger stores. They went out of business in 2004.
I was keeping my eye on a DVD reader and a DVD writer pair, but the prices remained a bit higher than I wanted to spend. One day, I decided I couldn't wait any longer, so i bought the writer. That purchase guaranteed the price would drop, but I never imagined it would happen in less than 24 hours!
I went back the next day to browse, and writer was $50 less. I talked to the owner, and he knew me as a regular buyer. Store policy was not to price match nor to give refunds for non-defective items, but he was nice enough to give me a store credit for the difference. The credit was enough to cover cost of the DVD reader's price which was also cheaper than the day before. In the end, I got the items I'd been wanting and for a much lower total cost.
I remained a loyal ByteWare customer for years until they went under.
