One card is enough
There is no minimum quantity and no minimum spend. A one-card Rookie Box is $17.99, prints on the same card stock as a full box, and ships in the same magnetic display case.
The one thing to know is the shipping rule: US standard shipping is free on orders $30+ and $5.00 flat below that, so a single card pays the flat rate unless something else in the cart brings the subtotal to $30.
Where fixed quantities apply
Two products have set sizes because of how they are printed. A Bulk Box is a run of identical copies of one design, sold in runs of 25 ($37.99), 50 ($64.99), or 100 ($89.99). A Rookie Box holds between 1 and 18 cards, each of which can be a different design.
A MEGA Card has no minimum either: one is $49.99, and the per-card price drops to $44.99 each for two and $39.99 each for three or more.
Teams and organizations
A coach can set up a team page and share a link at no cost; each player orders their own $29.99 pack, so the team never has to commit to a quantity up front. League and organization partnerships are free to join with no upfront cost and no minimums.
