HOW much for a bag of sand? I just bought a 50lb bag for $6.99 and was irritated because the last time I bought it was $5.

We bring our filter into the garage every winter (gets pretty ugly here) and a couple of years ago I had to replace the lateral, so I've had one complete sand replacment, and we do a little topping off every year because of the sand we lose when we move the filter. This bag will cover my sand use for next spring too (barring another lateral disaster).
