Thanks for the speedy answer, ok I must have missed the part about refunds.. I think the small box is the best value, the medium box is more than twice the cost of the small ones! It's bizarre, if you were pisting a lot of small things you'd surely choose to just use two boxes! you can fit a lot in a small box, if you just ordered bottles, not room sprays or melts/body cream.
Shame surface mail would probably be a nightmare for you! Although to send stuff from the uk it was only about 75pence cheaper when i looked the other day, insane!
