Hey, Lexie. I'm on clomid and metformin at the moment. The good news is that both are cheap - approx $20 for a box of clomid and similar for metformin. A box of clomid may do you two cycles, depending on your dosage, whilst a box of metformin lasts 5 weeks, assuming that you take 3 tablets a day (the max dose).

Hope that helps.
