The buck has stopped at Dollar Tree Inc. DLTR 16.49%

The retailer, which sells nearly everything for a dollar in its namesake chain, plans to add more products at slightly higher prices, highlighting the pressure on companies to offset cost increases for a range of goods.

Dollar Tree said it would start selling products at $1.25 and $1.50 or other prices slightly above $1 in some of its stores, expanding current tests selling items at higher price points as supply-chain snarls, a tight labor market and inflation push costs higher.
