I just received my mixed brick today, which I think is an ideal speed of delivery (just over two weeks). The box was a bit torn and damaged, but I'm never fussed with that if the seller packs the box well, and they did not disappoint! Decks were all in perfect condition. Additionally, The Blue Crown put the value on the customs declaration at a number that meant the package didn't get caught up in customs and give me a charge. I guess I shouldn't advocate that since it's illegitimate, but it sure tastes sweet to not have to go through that process!
Looking forward to using these decks as my new 'standard'. 12 decks should last me a good long time (I've only used four decks in the past 5 years).
