Domestic revenue of $10.84 billion increased 37.0% versus last year. The increase was primarily driven by comparable sales growth of 37.9%, which was partially offset by the loss of revenue from permanent store closures in the past year.
Domestic gross profit rate was 23.3% versus 23.0% last year. The gross profit rate increase of approximately 30 basis points was primarily driven by improved product margin rates, including reduced promotions, and rate leverage from supply chain costs. These items were partially offset by increased installation and delivery costs.
International revenue of $796 million increased 23.0% versus last year. This increase was primarily driven by comparable sales growth of 27.8% and the benefit of approximately 1,000 basis points of favorable foreign currency exchange rates. These items were partially offset by lower revenue in Mexico of $69 million, which was a result of the company exiting operations from the country, as previously announced on November 24, 2020.
International GAAP gross profit rate was 23.7% versus 22.3% last year. On a non-GAAP basis, the gross profit rate was 23.0% versus 22.3% last year. The higher GAAP and non-GAAP gross profit rates were primarily driven by improved product margin rates. The GAAP gross profit rate also included a $6 million benefit associated with more favorable than expected inventory markdowns in Mexico.
