Video game store

There was on of these shops near Connolly station in Dublin, don't know if it's still there. But it used to have every sort of old game and console you could think of at really good prices. It used to be packed whenever i called into it.

Must have a look someday to see if it's still open.

So i think it would be a good idea OP if you're still thinking of going through with it. Good advertising goes a long way.

Personally I wouldn't bother with a premises. This is the kind of thing you can run online, cutting down a lot of overheads.

1) Get a proper looking website, one with purchasing/basket/delivery options for buyers.
2) Back that up with an ebay account, & an adverts shop account.
3) Back it up further with a Facebook/Social media presence.
3) Spend a bit on advertising, it'll pay off.
4) Give buyers incentive, free national postage on orders over €20 etc. Take the hit, it won't cripple you, but your customer base will grow & in turn, so will turnover.
5) Keep your prices down as low as possible, as a seller, you need to stand out amongst the competition. As your turnover grows, so will your profits.
6) Don't focus on making money for the first while, focus on getting your name out there & being the best option available. Money will come later.
7) Pay attention to the little things, make sure games you sell are spotless clean & advertise them exactly as they are with multiple pictures.

Or, you could just take the usual approach:

1) Half arse everything you do.
2) Get your prices from ebay current auctions.
3) Have overpriced postage, if at all a postage option.
4) Don't bother with a website, sure everyones on facebook
5) Focus on making money, instead of growing the business.

Can't really picture a investment like this being sustainable or profitable, market isn't big enough and to make money you`ll need to price things higher than online auctions, where's the incentive for the consumer
