Do you BOGO? Well, you should, as there’s no cheaper way these days to nab a current-gen Android or iOS powerhouse. Make that two, since the very nature of a buy-one-get-one-free promotion compels you to pick up a pair of identical or similar phones, the most affordable of which is offered at no charge.

We’ve seen all the big four US carriers turn the BOGO tap on and off for the iPhone 6s, Samsung Galaxy S7 and LG G5 over the past few months, and Sprint once again wants to “keep your family connected over the busy vacation season”, presumably as it cooks up its second farewell to obsolete two-year pacts.

If you hurry, and don’t mind signing up to “at least” one new line of service, plus an eligible upgrade with the Now Network, every iPhone 6s purchase will net you a gratis backup. Or you can pay for a 6s Plus, and get a complimentary diminutive 6s. Last but not least, you’re of course free to acquire a duo of 6s Plus units, of which you’ll only actually foot one bill.

Talking numbers, your first 16GB iPhone 6s costs 24 monthly installments of $27.09 each with $0 down, and the second one is free after $27.09/month service credit. Similarly, you’re asked to cough up $31.25 a month for two years with no upfront fee for two 16GB 6s Plus copies instead of one.

Even better, iFans can save $200 on the “latest iPads” for a limited time with iPhone 6s or 6s Plus installment transactions or advantageous leases. If we didn’t know any better, we’d almost suspect a new iPhone or iPad was around the corner. That’s how sweet this deal is.
