The United States Postal Service recently introduced a new shipping product: the Small Flat Rate Box. Prior to now, small orders were sent using Priority Mail Flat Rate Envelopes, and could only accomodate about 100 cards without getting overstuffed. (Our cutoff from one pricing category to the next was 100 cards.) Now, with the Small Flat Rate Box, we can ship up to four hundred (400) bundled cards for the lowest Priority Mail rate.
All orders up to 400 cards will use the lowest rate (Envelope or Small Flat Rate Box). Orders from 401-2000 cards will use the middle rate (Regular Flat Rate Box). In the unlikely event someone orders more than 2000 cards, we will send using the Large Flat Rate Box, and shipping will be charged at the highest rate for Priority Mail.
To illustrate with a concrete example, approximately 36 expansion booster packs (11 cards each) can be shipped at the lowest Priority Mail rate. Before this, only 9 expansion booster packs could be shipped at that same rate.
