Not sure if any of you use the SiS gels, but check your inbox for a discount from USAC again. Either 12 free ones with $7 shipping, or spend $15 and get free shipping.
I paired mine with another BOGO in there somewhere and ended up with 24 total for $15.
Seemed like an OK deal to me. Just FYI if that's your jam or it would be worth it.
