On a hot summer day, there's not much better in this world than to take a dip in a clean, refreshing pool. Here's the problem: going to the public pool is noisy and comes with a cesspool of bacteria heretofore unknown to mankind. But buying and maintaining a pool can be outrageously pricey. Thank goodness for In The Swim. They've got pools and spas and all the equipment, chemicals and parts needed to maintain them -- all at prices that keep the budget from blowing up.
