Instructions:A couple of caveats, shipping ads about 15% to the cost, and import duties may apply. Yet the BOGOF deal makes the overall price about half of what you'd pay in the UK.
Some of the more expensive box sets have sold out on the first day of the deal (Complete Angel, Bond, XFiles), but 95% of the deals are still available and may not a bad way to fill out any gaps in your collection.
Some tips, place items of similar value into one order. Otherwise if you place two expensive ones and two cheap ones you only get the two cheap ones free. Its best to place two separate orders in this case. You may also need to manually type in the code at checkout as sometimes it does not carry over (it is <b> BOGOFOXMGM </b>)
