<prompt> Human: A couple more details. Im going to propose to my girlfriend before the end of the year. I currently have 9k in savings. I do t ha w to worry about the wedding cost, thank god. Her parents and mine will take care of it. The ring she really wants, and I want to give her, costs 15k and the store doesnt offer financing. I want to put it all on a new 0 interest card with the longest introductory rate. When the rate expires and I have paid as much as I can, Im going to get a loan for the remaining amount from my bank and use it to pay off the credit card before interest starts accruing. My question is, what is the best credit card with the longest 0 introductory rate out there?Edit: I guess more clarification is needed. The 9k Ive saved is specifically for the ring. We already have a house together. I could get a loan for the 6k difference right now, but I would rather use the 18ish month 0 introductory period to save more so when I finally get a loan its only for 3k. If you disagree with the amount of money Im spending, thats okay. Thanks for all the help and general life advice.  <response>: I just got divorced over finances mostly. Do not buy this ring. If she doesnt understand that its a HORRIBLE purchase decision, you will have financial problems for the rest of your life. There is a very good reason the store doesnt offer financing: customers that can afford it will pay cash. Customers that cant, wont, and itll go to collections... Theyre avoiding that trouble. You see the ring is a gesture of love, but going into debt for it is a death sentence for your marriage.Do. NOT. DO. IT.
