When the exchange rate is favorable like it is now, buy your Wheatley boxes directly from Wheatley from their UK website like I do.

At the current exchange rate a 32 compartment 1609 will run you about $100. You don't pay the VAT and the shipping from the UK is really reasonable and doesn't take too long. You will pay your credit card company an currency exchange fee of a few bucks but you still will save a TON over the inflated fly shop prices.

Wheatley service is excellent too!
