Stockpiling & Freezing: Meat, Found $70 worth of meat for $30

So I was in Sunmart to get a quick item: hamburger and what I found was meat on clearance. So I snagged $70 worth of meat including my 80% lean hamburger for $30. How awesome of a find. When I find meat like this I dig out my marinade and seasoning mixes which these cost with coupons about $.20-$.40 ea.
 I would then pair it up with the meat I want to use with it like the picture below:

Then I will either chop it, cube it or leave whole

 

Then I would mix up the marinade or spices and pour into the baggie along with the meat.

Here is just 3 bags complete and ready for a meal:
1-has just bbq spices
2 of the bags have marinade in it.
Freeze and then pull out for a meal 24hr before, let it thaw in bag and every so often just kneed the spices or sauces. Once thawed dump entire contents into pan and Cook.
