<prompt> Human: I am looking to spend in the 5000 range and should have enough cash saved up to pay for at least 80 of it, but was wondering what the best strategy is.Should I get a credit card with a 0 interest introductory offer that will earn me pointsmiles since I shouldnt have any trouble paying it off in full in the introductory period? If so, are there cards people recommend for such purchases? For instance, something with a spend X thousand dollars in the first 3 months and get Y dollars back?Should I just take an offer like Blue Niles where theres no interest on the purchase if paid in full within 12 months?Any recommendations on these questions or any related questions that I might not be thinking of would be greatly appreciated.Edit: Okay, I get it. Lets say Im spending 4,000 and have all the cash to pay up front. Is it still worth putting it on a credit card? Or at least putting some of it on a credit card up to a certain percentage of my credit limit?  <response>: Not to finance it.
