<prompt> Human: Question is as the topic suggests. My girlfriend and I are quite serious and getting married is some we have discussed at legnth. Id still like to try and make the proposal a surprise. Weve even discussed how much should be spent on a ring, but Im still not sure how to pay for it. All our accounts are shared, I do have some credit cards I could charge it to, or perhaps I could finance it through the seller. We keep a healthy amount in the bank that I could pay it off with cash from our main account after the proposal. I suppose as long as I paid it off after only a billing cycle or two the interest would be minimal. Any ideas?  <response>: If you and your girlfriend have discussed this before, you could ask her next time the topic came up.If youre trying to hide it though, here are a few thoughts: Open a new card that she doesnt know about. Direct deposit a portion of your paycheck into a new bank account - this could be helpful if you have a raise or bonus coming up. Borrow the money from a friend or relative until you propose, you could even write them a check and have them hold it. Debit transactions and skim some cash back - although this probably wont be able to generate money fast enough. Side jobs for cash. Sell some things that she wouldnt notice were missing.
