''Try and get close to CRC/Wiggle prices if needed
Why laugh. Better to buy off them when they do deals or as needed if cheaper than your suppliers add a bit from their normal CRC price or wiggle who are a bit more expensive and gain customers and word of mouth base and experience than to do nowt and sell nowt. And I said as needed, try work out if they know of these online shops. Average Joe does not, only the bikers do.
You'll not be making money for a while anyway until the business gets larger and more popular.
Diversify as well if you're in a good location. Stock various cell batteries cheap of eBay, people might need them for toys and things. Get this known about. You masked nothing from them but gets people into the shop and the name known.
It all depends if you want to sit back and hope it happens or go out trying as hard as you can. Don't piss the youth off and stock trials/bmx if that is what theory are using, see if you can get work experience kids in when it is possible.
All just ideas of course.
