I'm aware that some of my prices are high for an international market but they're priced to be competitive in the UK market; I paid shipping over here and in order to break even/ turn a profit, I need to raise the price. In saying that, taking on board shipping from the US or further afield, it IS competitive in the domestic market.
The cards are printed in the US and in order to avoid taking massive losses, I need to compensate for the shipping I originally paid. Basically, I will have trouble competing internationally and this is also why the prices are in GBP (£ sterling); you may be able to get better prices from other resellers if you're not geographically close to me. Some of the stuff is hard to get, and that's where the international market comes in.
In regards to the v6, they are getting more and more rare and while you might be able to get them (ever so slightly) cheaper on eBay, most of those are Hong Kong auctions and thus the waiting period for receiving the deck is greatly increased. I've priced other items similarly in regards to waiting time for European buyers.
