Hi Chrissy

The Double Dipping that you've read about here is really only a cause for concern when someone uses two or more US consult-based OPs simultaneously. Many, many DB members order from multiple Int'l OPs at the same time. I don't know UK law but if its anything like it is in the US I really wouldn't worry about your packages clearing customs within a short time period of each other - you're actually probably more likely to receive at least one order if others are seized.

Good luck!
