Besides getting some extra mags, get a General Purpose Knife. I got one with my coupon and have carried it ever since. I ordered a few other things also, including a holster, mag pouch and bushing wrenches. Never did get the mag pouch, come to think of it.
Good deal is a relative term. I’ve used the coupon three times to date. Still waiting on the order for the last one. The magazines are a good deal, they work well in all my 1911’s and the price is right. One thing is they don’t come with a slam pad. The Otis cleaning system is a good price and I like it. I’ve two of the lined nylon holsters and they work well for what they are designed for. In short, most has some description on the Springfield web – page and the prices are very good with the coupon. I’m waiting for 10 more mags another Otis system, a knife, range bag, and a cleaning rod.
I got the General Purpose knife and am quite pleased with it for the $20 or so it cost. Seems to hold a good edge; I thought I read somewhere that it was Solingen steel but the knife doesn't have that marking.
I also got 3 extra mags and a bushing wrench. The mags work just fine and have never had a problem with any of them. My coupon also showed some binoculars for cheap so got those too. They are a cheap Simmons 8x40, not the best in the world, but good enough to keep in the truck.
