Money Savvy Monday: Buying in Bulk

So to save some dollars there are a few things that I will buy in bulk. One of my favorite items to buy from Sam's Club is laundry detergent. I use Cheer liquid detergent.

At Sam's, I get 110 loads for $19.02, which is 17 cents a load.
At Drugstore.com they have a 32 load bottle for $12.99, which is 41 cents a load.

I wash around 10 loads a week, so this saves me approximately $115.00 a year!!

Let me know what you do to cut costs.
