I have been ordering Hill's senior light. If you order 3 or more bags, the price comes down to £6.81 per 1.5kg bag (From just under £11)- I had a delivery from VetUK yesterday and there was a free sample of adult food with a leaflet for a code for 20% off Hill's Science Plan food. There is no mention of "Cannot be used in conjunction with other offers". When I saw it, I wondered if the other offer had finished, but I just checked and it is still on. I haven't tried ordering and checking out, but I can't see why the double-discount won't work - worth a try anyway

- anyway, The code is HSP120 - expires 31st August. (Excludes VetEssentials)
I doubt if it will work with prescription diet as it isn't branded as Science Plan.
If the code works, it should work out around £5.40 a bag which is less than 1/2 price
