Secondly, people need to STOP being so negative about the prices, its difficult to source retro games at a decent price and then price them in a way that you make £1 - £5 profit on an item and them another percentage to cover overheads such as lighting, electricity, food, cleaning products, furniture, money for new stock.
Thirdly, when you have a basic staff of only 2, wages are needed to be covered, hence prices will be bit more than ebay due to all of the above overheads.
I'm sorry but no. When a shop (not saying this one is) is selling items at prices above Ebay then they are asking for trouble. Consumers are struggling with finances as much as business at the moment, money is very tight. You need to make the business attractive to punters, especially if you need to travel to get there. People are not complaining either, it is called feedback.
Retro games may at times be hard to get hold of, but also with things like the car boot sale, you can pick items up and sell them on for huge profits.
