Enspire just sent out $40 OFF coupon for Prime members, but it works for everyone.
Use coupon code "ENSPIRE40".
If you're not already on 15% OFF S&S, use cheap S&S items to meet minimum qty of 5. You can browse the S&S items from:
If you're lazy, this thread might help you.
So, all in all:
Item Price: $189.99
Subscribe & Save: -$28.50
Enspire Coupon: -$40.00
Amazon Coupon: -$25.00
If you only get 5% S&S, then it'll be $20 higher, so use the fillers to get maximum savings.
This probably is the cheapest price on Enspire formula ever, at least from what I've seen.
