Currently there's no allocation system set up BUT we do limit quantites to one each time. For example, you couldn't place an order for 2 Nintendo Wiis, only 1. You CAN place an order for 1x Nintendo Wii and 1x Wii Nunchuck and 1x DS Console for example.
So technically, you CAN go mad and order as much as you like but it would be very tedious.
We've tried to think of every scenerio here and will obviously live and learn throughout the store's opening. Mistakes are unfortunately bound to happen and stock may indeed run short. We have incorporated this into the site's terms & conditions. I think allocating certain items is probably the best bet. I'll look into that now actually. Thanks for the tip
