Regardless of which courier you use, if you order just two to three
small to medium size bottles at a time, they will usually let it go.

I introduced this woman in my office to Nature's Best UK some years ago.
She had no problem bringing in their glucosamine and chondroitin sulfate,
quite big bottles of 180 too, around two at a time.

She then bragged about their really cheap price to some relative or friend
who then conveniently asked her to order extra bottles.

Without thinking, she promptly ordered 4 bottles, which were all confiscated.

If you order several bottles of the same product at a time, they will think
you are some distributor or retailer.
