Hanes

With Hanes, the math that matters is cost per piece, not the sticker on the pack. A larger multipack almost always beats a smaller one on a per-unit basis, and the underwear and sock categories tend to take the steepest percentage cuts during the brand's sale events — so buying the bigger bundle during a promotion compounds two savings at once. If a size and style you rewear is on sale in a big pack, that's typically the moment to stock up rather than reorder singly later.

Two channels help push that per-unit number lower. Signing up for Hanes Rewards has commonly triggered a welcome code (reported around 15% off a next order), which layers on top of a multipack discount. And the brand's own outlet and clearance sections — online, plus physical HanesBrands stores you can find through the site's store locator — routinely undercut the standard catalog on discontinued colors, prior-season styles and overstock. Because Hanes basics don't change much year to year, last-season stock is functionally identical to current stock, so clearance colors are one of the lowest-risk ways to buy here.

One practical note on shipping: like most apparel sites, Hanes has gated free delivery behind an order minimum, so consolidating a few packs into one order rather than buying piecemeal often clears that bar and avoids paying shipping on each small purchase.
