Heres a process that might be able to get your order fulfilled. Go to sealswithclubs.eu, the bitcoin poker site. Join the site and talk in the main chat, people generally are always selling chips for moneypaks of $200 or less. In the chat there is also a bot that will tell you how much $ is equal to in chips. 1 BTC = 1000 chips. Then withdraw your chips for BTC to whatever BTC address you have. Withdraws are ALWAYS sent within 12 hours from time of request.

Type in "bpb 170 usd in chips" and it will tell you. Ask chat if anyone will sell for that many or ask for offers. Use a trusted Escrow, if you see me on there I can help and escrow.

Anyways good luck to you. Also look in the currency exchange section of this forum and you might find a thread for selling for moneypaks.
