That's right, I used to buy 2 van loads of lawnmowers and chainsaws and what ever also each weekend in this manner, it's alright if you have money because you might get good ones one time and make a profit but then get a load of crap ones next time and loose money. I stopped it because I had 2 van loads of basically scrap and I lost too much money.
It's just a fun lottery Parwaz.
Why don't you buy 10 at a time and see how it goes?
