MJ Holdings Pokemon Mystery Boxes aren't ALWAYS trash!

I open two type of Pokemon mystery boxes from Walmart both costing about $20. I find that MJ Holding tend to put pictures of chase packs that you'll never pull some times the chase packs are good but most of the time you'd be better off buying a collection box or single packs knowing what your getting. Pulling $12-$18 in value most packs going between $3-$4 and Evolving Skies costing around $7.50
