I see the line of "they showed me an ad for X after I bought one on their site!" thrown around a lot as a sign of incompetence, but the fact you made the purchase recently actually makes you a good target demographic.

You wanted some good and paid money for it. There's is now a real chance that the good you bought did not meet your needs, it broke it sucks, etc. If so, you're a prime target for these ads. If it broke you're probably looking for a new brand, or maybe it just isn't that great and you're considering returning the item and making a new purchase. While you may not need one you're part of a demographic that responds well to these ads relative the rest of the population.
