Not knowing what the original price is, I'll assume since you posted it's a good deal. One thing I'd be weary of, especially at Walmart/Target, is the fact that pack searchers have likely been there. I went into my local Walmart here once and some of the packs were even slightly opened. It was hard to notice, but still noticeable. I pointed it out to an employee but, of course, they couldn't have cared less.
So, cool on the good deal, but I wouldn't expect any "hits" in any of those packs regardless of what the odds say.
Those packs are great for people trying to build a complete set of anything. I've used them before when I was collecting non-baseball Allen and Ginter minis. If you're going for "hits", though, it's just not likely going to happen.
