Some great bargains to be had, from around £8, if corsets are what you're looking for. The Pink/black polka dot corset pictured was £64.80, now £24. (Bigger reductions within, but liked the look of that one :D).
The budget option for shipping is £2.40, not sure if it varies depending on the weight of the item.

Edit: Thanks to Hissy Miss to pointing this out: "It says 3 for 2 which it doesn't seem to give but price comes down further when you add 3."
