Hi,
I'm living in UK. I currently handling those deals sites for several customers as well as doing fulfilment services / return accept services on behalf of them.
I can do this job as I have experience with UK deals websites. I have followed several projects for clients who do eBay / eCommerce websites as well as amazon.
I will provide you better output if you choose me. Further more if you are planning to do with groupon, then there are some requirements to full fill (they ask merchant to do). I will assist you with those things as well.
