Prime Day wraps up tonight, and if you've been sitting on the fence about an Apple purchase, consider this your nudge. A deal roundup over at MSN walks through 16 Apple deals a self-described tech geek says are actually worth the money before the clock runs out at midnight.

Now, I've watched a lot of these sale events come and go over the years, going all the way back to when a "doorbuster" meant standing in a cold parking lot at 5 a.m. the day after Thanksgiving. And I'll tell you what I tell my family: a discount on something you don't need is still money spent. But Apple gear rarely drops much below list price the rest of the year, so when it does I pay attention, and you should too.

The roundup covers the usual suspects, AirPods, iPads, Apple Watches, and accessories, the kind of stuff I get asked about every holiday season anyway.

A few things to keep in mind before you click buy, and these are my own rules of thumb, not anything from the source. First, check the model year before you checkout. My observation over the years is that retailers sometimes use big sale events to move older gear, and that can be a fine bargain or a dated one, depending on what you need. Second, if a deal is on a device you were already planning to buy, that's when you pounce. Technology should work for you, solving real problems, not tempt you into impulse purchases you'll regret by Friday.

And if you're buying an iPad, my standing advice applies: a tablet should earn its keep with real productivity tools, not just streaming video in a bigger box.

The deals end at midnight, so if something on that list matches a genuine want or need, don't dawdle. When the event ends, these deals end with it, and nobody wants to be kicking themselves, mildly, while paying full freight.
