As of 2015, HP maintains an online store where it sells ink and toner cartridges for its printers. Customers can identify appropriate products for their needs by searching for cartridge numbers or printer models.
As of 2015, customers who purchase cartridges directly from HP receive their purchases the next business day without paying any shipping charges. HP also offers a supplies finder that allows customers to identify retail stores where they may buy replacement ink.
Customers may also buy ink from a retailer other than HP and receive promotional offers. Examples include free shipping offers, just as with HP, along with cash back rewards through the Staples Rewards program or discounts through the My Best Buy rewards program.
