You might check PCBshopper for competitive prices. Just put in your board size and qty of 3 (OSHpark sends 3 bds, and the others will default to 5) Bump the shipping time to longest time for cheapest cost. Last 5 boards I ordered were $4.35 shipped (JLCpcb). OSHpark is $5 a square inch, so they can be the best deals for very small projects. No need to pay those high shipping costs.
