Lol, it's quite interesting reading some of the comments on this thread, thankfully as me and Rich are friends I know that the original post wasn't about me.
I don't mind being the first trader to chip in with a comment though, I'm not one to ask for feedback nor do I ever not put prices up.
Having spent 9 months out of my life looking at pricing I can tell you it's difficult, you can never be the cheapest on every single item you sell, it's just impossible you have to work on margins, competitors and risk.
I can only comment on my own business, I've been doing it for nearly three years now, I only wanted a few extra quid to pay for car stuff and for the vast majority of time I worked one or at times two other jobs while not ever taking a wage from Tarmac Sportz. I'm quite proud that I started with nothing ( literally 5 sets of bonnet lifters ) and reinvested every penny back into the business, I still have nothing lol but I do have a business that should grow from strength to strength fingers crossed.
Rich personally knows the hours upon hours I have put into this business, I haven't managed a lads night in about two years, I research as best I can and I price most things cheaper than buying direct from the US, it won't always be the case obviously.
What I would say being in the position I'm in is try it. It doesn't cost much to be a member trader £25 a year. If your successful you may even get a subforum .
