My family started taking probiotics this summer. I first bought them at the local health food store. A package of 30 capsules was about $18. That is $0.60 per capsule. We all shared a couple packs with in a matter of weeks.

I decided if we wanted to continue to take them they needed to be less expensive. I found the brand we liked at Amazon.com! The packages were 90 capsules for $18.60! That is $0.21 per capsule. A savings of $0.39 per capsule.

I signed up for Amazon's Subscribe and Save plan which locks in the price for all future orders AND provides free shipping. I now get three packages of 90 capsules every 90 days. Originally, I signed up for four, but my husband keeps forgetting to take his...so I adjusted the order amount. I can change it later if needed.

To reduce the amount I pay every 90 days I use my swagbuck earnings towards Amazon gift cards. I earn them in $5 increments. Since the last order I earned $20 in gift cards!! I also had $2.60 left from another order.

Here's the breakdown of our current probiotic shipment:

3 90 capsule probiotic packages = $51.36
(price dropped to $17.12 per pkg)
Amazon gift certificates applied = $22.60
Total out of pocket = $28.76
Price per capsule = $0.11

The savings over local store for the three of us is $0.49 per capsule. Or $132.30 every 3 months. Or $529.20 per year!! Geez.

I'm going to keep earning swagbucks just to help keep the cost savings down. Works for me!
