I love Buyology, Poundstretcher and B and M Bargains. These are all in the retail parks in Newport. Home Bargains has the cheapest Angry Bird Star wars stuff around, even cheaper than Asda!
Poundstretcher is great for tins of nice biscuits for teachers etc.
I can't go in The Range as I find it really impossible to leave without buying anything. And by anything, I mean more than I can physically carry.
What's your Christmas Bargain Top Tip?
