I set the price according to offer and demand going on aswell how the service works, delivery is instant if I am online or take less than a few hours in case of being offline. Coins are also immediately transferable to anywhere.
Its uncommon to see that price of $6,5 per 250 tcs, usually it is set at $9. I do also offer greater amounts of tcs with lower price (discounts). Paypal is accepted.
