Find the Promo Code box in the upper right of the Cart page on In The Swim. Enter your Promo Code and click Apply to use it on your order.
What's In The Swim's return process?
In The Swim offers a 30-day return window on most unused items in new condition and original packaging. Returns can be initiated online, though oversized items may carry additional shipping costs, and shipping and handling fees are non-refundable unless an item arrives damaged or defective. Refunds are typically processed within a week, while custom orders and select chemicals are excluded. Damaged or defective items must be reported within 30 days to qualify for replacement, after which the manufacturer's warranty applies.
In The Swim offers fast shipping through FedEx within the 48 contiguous states, with most in-stock orders placed by 4pm CT shipping out the same day, which is a great perk for shoppers seeking quick delivery. While many orders qualify for free next-day delivery, this is not guaranteed and can be delayed by holidays or weather. Expedited shipping is available for an extra fee on select items, and larger products are delivered curbside by truck, requiring a signature.
In The Swim's order cancellation policy is somewhat restrictive for shoppers, as you must call customer service to cancel and can only do so before the order ships. If your order is already being processed or shipped, cancellation is not guaranteed and you'll need to use the return policy instead. This policy may not offer the flexibility some online shoppers expect.
In The Swim offers shoppers valuable savings during seasonal sales like summer, Black Friday, and Christmas, often with discounts of 20% or more on pool and spa supplies. Their website also features Daily Deals for extra bargains. Signing up for their email newsletter is a smart way to stay updated on the latest promotions and maximize your savings.
Does In The Swim provide Buy Now, Pay Later financing?
In The Swim gives shoppers flexible payment options with Affirm, letting you split purchases into manageable payments with clear terms and no hidden fees. You can also use a 6-month layaway plan for in-ground pool kits by paying only a modest fee, making it easier to budget for big buys without extra surprises.
