Walmart is holding a three-month “Rollback” on iPhones and Galaxy smartphones.

Starting Friday, customers can save $100 on all Apple iPhones or $150 on all Samsung phones through the end of June.

Not every store will carry the same models, but the discount applies to all of the latest devices — including the iPhone 6, 6 Plus, 6S, new four-inch SE, and the Samsung Galaxy 6 and 7.

Walmart is working with AT&T (T, Tech30), Verizon (VZ, Tech30) & Sprint (S) on the deal, so customers will see the discounts through their bills. Unfortunately, T-Mobile (TMUS) customers won’t be able to take advantage of the promotion. The deal is also not available for online purchases.

Apple (AAPL, Tech30) launched its newest iPhone — the SE — last week. At $399, the 16 GB model is the cheapest smartphone in the company’s lineup.

The SE becomes an even more attractive option with the Walmart discount — especially for people who want a newer iPhone but don’t want to spend half a grand.

The SE looks nearly identical to the iPhone 5S, but takes better photos and videos, and has the same A9 chip and M9 motion processor as the newer iPhone 6S.
