Saw this on other forums, since im not active on the other ones, I though I would start one here.
Incase you arent aware Playasia usually send coupons with your order, so the usual method to this is, you use a coupon given to you, get your order and a new coupon, share coupon with another person seeking to place an order and the cycle continues.
Ill go first, if anyone has a coupon they arent using, I would be ecstatic if you would send me the code, ill then pass on my code to someone else.
