This will help:

comprar [A1] verbo transitivo
A ‹casa/regalo/comida› to buy, purchase (formal); comprarle algo a alguien (a quien lo vende) to buy something from somebody; (a quien lo recibe) to buy something for somebody; le compré estas flores a una gitana I bought these flowers from o (familiar) off a gypsy; ¿quieres vender el coche? ¡te lo compro! do you want to sell your car? I'll buy it from you!; les compré caramelos a los niños I bought the children some candy, I bought some candy for the children; se lo voy a comprar para su cumpleaños I'm going to buy it for his birthday; comprar algo al por menor or al detalle to buy o purchase something retail; las compran al por mayor they buy o purchase them wholesale; comprar dólares a plazo fijo to buy dollars forward

Edit: that doesn't help at all. It could mean either.
