Si compró I agree with most of Nathaniel's answer. The better choice of verb form for "comprar" is the pretite.
However, think that instead of "usted podría" (the conditional form), maybe the subjunctive "pueda" would be the grammatically correct choice. I'm not sure myself, but since the English "could get" is the intended verb, uncertainty is implied - not just a stated condition to warrant the conditional tense - I wonder if the subjunctive should be used. Perhaps, hopefully, someone more knowledgeable might be willing to instruct us on this point.
