Spectra Sure w/IGR Flea Meds

I work on the website http://www.duboisdistributors.com/ they added new flea control products and I just bought some for Peanut & Bailey. Spectra Sure w/IGR has the same ingredients as Frontline Plus but is only about 1/2 the price! I looked online and a three pack for the same size of Fronline Plus sells for $40 - $46. I bought this at Dubois for $21.47 with free shipping. I'm so glad there is now a resonable flea control medicine that actually works. This protects against ticks as well which is a growing concern in our area. We do sometimes go for walks in the woods. 
They also have a cat version. I will be buying that soon since all 3 of my cats go outside.
