Before you buy GHD hair straighteners off Ebay, think again. Ebay does not necessarily mean you are going to get a bargain AND the postage is often quite high.
I DID look for the limited edition purple GHDs on Ebay and found new ones around £120 - 130 price tag. Not too bad when the rrp is about £155.00. Delivery was extra. HOWEVER I found the best price of £93.92 with FREE delivery on another ordinary retail website.
I do buy a bit off Ebay but if it's new, I always check out other websites and take the P & P into account too. Always, always, always check out other sites before you buy anything new!
