PriceSmart, Inc. PSMT reported impressive sales numbers for January. In fact, the company reverted to positive comparable net merchandise sales (comps) after a dip in the metric for December. Apparently, comps for the four weeks ended Jan 24, 2021, edged up 2.8% for 45 warehouse clubs. Comps were hurt by foreign-currency fluctuations to the tune of $7.7 million or 3.3%.

Consolidated comps rose despite decreases in Colombia and Trinidad. In fact, comps across Colombia were marred by rising restrictions on circulation owing to increasing coronavirus cases and impact of sales transferred from the existing clubs to the company’s newly opened Usaquen club in Bogota. The metric in the Trinidad market was mainly hurt by management’s decision to limit U.S. merchandise imports on the insufficient U.S. dollar liquidity. Nonetheless, PriceSmart is trying alternative solutions to alleviate the ongoing illiquidity challenges in Trinidad.Considering the pandemic woes, the company lost nearly 70 club days in January, where in-club shopping was forbidden.
