Without pools, sweltering children would be forced to take turns cooling off in glasses of iced tea, one digit at a time. Celebrate full-sized swimming holes with today's Groupon to East Coast Pool Supply, with five locations in Jupiter, Royal Palm Beach, and Stuart. Service-area boundaries are West Palm Beach to the south, Stuart and Palm City to the north, and Wellington to the west. Choose between the following options:

• For $10, you get $20 worth of pool supplies and toys.
• For $37, you get a one-hour service call (a $75 value).

East Coast Pool Supply employs a staff of knowledgeable associates and trained repair technicians with the skills to ensure that clients' personal great lakes stay in prime swimming condition year-round. The pool professionals' storefront boasts a surplus of pool-maintenance equipment, parts, toys, and other chlorine-ready goodies for your perusal from brands like Jandy, Hayward, Pentair, Bioguard, and Zodiac. Inflatable sea animals abound in shapes like sea turtle, alligator, whale, and Crocodile Dundee ($12.90). An easily installable wall fountain ($24.90) and spring float lounger ($24.90) turn a dull day by the pool into a tropical oasis. A selection of chemicals, such as a 2.5-gallon chlorine refill ($4.25) and one pound of pool shock ($3.99), fend off algae, microbes, and unwanted merman houseguests.

Alternatively, those with pool predicaments let East Coast Pool Supply's state licensed and insured technicians take a gander at oversized baby pools during a service call lasting up to one hour. The piscine professionals diagnose non-operational natatoriums, stop pumps or filters from leaking, and offer operational instruction to new pool owners who have yet to get their flippers wet. If needed, parts and additional service time incur an additional charge at the time of service. Although above-ground pools and hot tubs help create some of the most talked about high-school memories, they are not available for service with this Groupon.
