Just wanted to pass this along in case you were making guacamole, margaritas, or something lime-y this weekend.
Hong Son Oriental Food Market has great looking limes available 4/$1. (update: 11/15/09 now they ar 5/$1)
Hong Son is located in historic downtown Rogers on the corner of W Cypress and 7th Street (next to the Boys & Girls Club). Hours are 9am-8pm every Tuesday-Sunday (closed Mondays).
