Walmart offers the Schwinn Frame-To-Floor Bike Pump for $5. (Amazon charges the same with orders of $25 or more.) Choose in-store pickup to avoid the $5.99 shipping cost. That's $4 under our mention from last October and the lowest price we've seen. (It's also the best deal now by $10.) It attaches to your bike's frame and converts to a floor-style frame for easier inflation.
