We got them for $6 from China on eBay. Shipping takes about a month (and is free), but as long as you plan ahead properly and commit to buying early then you can save a huge amount of money. In fact, I don't think a single fastener on our robot came from outside of China (aside from KOP and Vex ones obviously). Paying Lowes or Fastenal prices for anything other than stock metal just wasn't in the budget for us.
I'm interested to know the quality difference between the ones we got and a $45+ coupler from McMaster.
