The trick is to route underwear/innerwear official mail-order and online specialty stores through a point site, consolidate periodic replacement and seasonal items (thermal innerwear, summer wear, etc.) bulk buying via routing, route the whole family's at once, and pay with a rewarding payment. Frequent replacement and large family-bulk amounts make cashback easy to stack. This guide organizes underwear/innerwear point-earning by official routing, periodic replacement/bulk, and payment cashback. Read it alongside the fashion & apparel guide and the detergent & daily-goods guide.
