In the mid 2000s being a young teenager with zero income I couldn’t afford pro boards or even had a local shop to go to. I’d save money from Christmas and my birthday, and in the summer cut a few peoples lawns and I used to buy a stack of blank boards off eBay. I think it was like 5 for 65 bucks. They were the worst boards I broke someright after setting them up on flat ground tricks, but I did that for about a year or 2. Occasionally I would sell one or 2 20 bucks a piece to a kid in the neighbor and have enough to get a normal board.
As a kid who mostly skated mini logos, atm, or any board that was marked down, maybe it was warped or just ugly and didn’t sell. I solely relied on anything I could afford that was on sale.
However if you’re an adult who pays rent and bills I think you can afford to buy regular skateboards and just give up on being sponsored, because you’ll never be good enough to make money off it anyways.
