Can anyone recommend a reputable online supplier for advocate spot on flea treatment?

Title says it all really. I've treated our 3 cats and 1 dog with advocate purchased from our vet, but it cost me £106 for 3 months supply so I'm hoping to find a cheaper source!!!!

I just went on quidco for ours and found the cheapest supplier with the highest cashback.

The vets private prescription cost £8, it works out at about £4 per month for one cat.

I have bought from pets at home online but I dont know if they would be any cheaper!
