Good experience


Purchased 2 off scalibor dog collars in May at the total price of £31.
Went to order a further 2 off in Sept for my holiday price had gone up 62% to just under £60 total. When I queried they just said that's the new price.
Went to another online vet practice and bought 2 off for £36 total price.
Good bye and farewell to rip off Bob Martin.


First class service, products reasonably priced and quick delivery.


Excellent service and choice of products, delivered the next day


Quick and efficient and I was contacted very quickly when there was an issue to sort out


Their website was reasonably clear and the purchase procedure was speedily completed.


Two of my items were not sent, it took multiple emails to finally be told my missing items to be sent, almost a week later they hadn't arrived. So sent another email to be told it had been sent and to email again in two days if they still hadn't arrived. To get a phone call less than an hour later to say it hadn't been sent and one product wasn't on sale anymore. I was then finally sent my missing products. Not great customer service having to send two emails to get a response and to be lied to.


Bob Martin had everything i wanted and delivered it very quickly. But what's just as good was their prices were lower.


Very easy and efficient web site, easy to find and order the right product. Delivered on time. What else is there to say. Would recommend to all and use them again myself.


Certainly recommend advantage for cat fleas , no issues or problems with fleas at all .


Excellent service, good delivered in a matter of days. Good products at a reasonable price
