Frequently Asked Questions

 

Discounts generally cannot be combined with other offers, and codes typically don't apply toward shipping, handling, freight fees, taxes, or previous orders, so it's worth comparing a Daily Deal price against a sitewide code applied to a different item to see which saves more.

Check that the order meets any minimum spend tied to the code, since several In The Swim codes only apply above a set dollar amount, and confirm the code hasn't expired, since many are tied to specific seasonal sales.

Unused, unopened products in original packaging can be returned within 30 days of purchase for a replacement or refund, and eligible returns come with a prepaid FedEx label sent by email.

Calcium hypochlorite shock, liquid chlorine, muriatic acid, and other hazardous chemicals cannot be returned or exchanged due to shipping restrictions on hazardous materials. Custom orders, including safety covers, spa covers, and pool liners, are also excluded, along with used or installed equipment like pumps, filters, heaters, and motors.

Outside of the standard 30-day return period, damaged or defective products fall under the manufacturer's warranty instead of In The Swim's own return policy, so a claim would go through the manufacturer directly.

Cancellation requires calling customer service and can only be done before the order ships. If the order is already processing or has shipped, it's no longer possible to cancel and the standard return policy would need to be used instead.

Free standard shipping is available on orders over a set threshold within the continental United States; In The Swim does not ship to Hawaii, Alaska, or overseas U.S. territories.

Yes, Pool Perks lets members earn points on every purchase that can be redeemed for discounts on future orders, which layers on top of any active promo code.

Saving Guide

Because hazardous pool chemicals and custom orders fall outside In The Swim's standard return policy entirely, planning those purchases carefully upfront matters more than trying to fix a mistake with a return later.

Ordering hazardous chemicals in the right quantity the first time

Since calcium hypochlorite shock, liquid chlorine, and muriatic acid can't be returned at all, calculating pool volume and chemical needs carefully before ordering avoids being stuck with excess product that can't be sent back.

Building points through Pool Perks on regular chemical orders

Because pool maintenance involves recurring purchases throughout the swim season, joining Pool Perks before placing a first order means even routine chemical restocks start contributing toward future discounts.

Checking the outlet locations for heavy equipment

For pumps, heaters, or other bulky equipment where shipping costs add up, checking whether a nearby In The Swim outlet carries discounted overstock can save more than a coupon code would on the same item purchased online.

Timing bigger equipment purchases around Black Friday or summer sales

In The Swim's steepest markdowns, historically up to 60% off on select items, tend to land around Black Friday, Cyber Monday, and early summer, so planning a heater or robotic cleaner purchase around one of those windows can beat a standalone code.

Confirming custom order details before submitting

Since custom items like safety covers and spa covers can't be returned or exchanged, double-checking measurements and specifications before finalizing a custom order avoids a costly mistake that can't be corrected afterward.

Checklist before checkout

Confirm the order meets any minimum spend for an active code, calculate chemical quantities carefully since hazardous products can't be returned, check Pool Perks point balance and whether it can offset part of the order, and verify custom order measurements before submitting.

About In The Swim

In The Swim has supplied pool and spa chemicals, equipment, and accessories directly to consumers since the 1980s, when the business started out shipping pool chemicals from a garage before growing into a major direct-to-consumer retailer now owned by Leslie's. The catalog spans everything from chlorine tablets and pool covers to robotic cleaners and heaters, and the company also runs physical outlet locations carrying discounted overstock equipment. Shoppers can find current In The Swim coupon codes and discounts on this page, useful for stocking up on pool chemicals each season or replacing aging equipment for less.
