To purchase goods in large amounts with the plan to sell them again at a higher price, often at the same location.

Past: regrated
Past Participle: regrated
Regrate is derived from the prefix "re-" (meaning again) and the root "gratare" (from Latin "gratus", meaning pleasing or agreeable). The term originally referred to the act of buying up goods to sell them again, often at a profit, thus implying a repeated action of trading.
Think of 'again' ('re-') and 'pleasing' ('gratus') to remember that 'regrate' means to buy goods again for resale.
