Hello,
My name is Sam and I'm the marketing manager in charge of the giveaways for UPrinting.com. I'd love to explain our giveaways and why we do them.
1) Before I was a marketer, I was a blogger. I know that a blogger's voice means a lot. I have no problem giving a product to a blogger and having them broadcast what they think. Especially if I have a good product. Give it away. The word of mouth marketing is better than anything out there if you have a good product.
2) Why so many giveaways? We like bloggers and a LOT of bloggers like us. If you have a real blog with real readers, we're interested in offering you a product review or giveaway. Google "Blog Sponsor" and you'll find this somewhere on the first page
http://www.uprinting.com/blog-sponsor-program/ <-- its our sponsorship application form
3) Why 250? Its our minimum quantity for Offset printing (the best color quality). They are great for your small business. That's why 250.
4) Do people receive prizes? Why not ask the bloggers themselves? Why not search @uprinting on twitter? You'll see that our prizes are awarded and we have a full time team dedicated to helping bloggers get those prizes to their readers.
5) We are legit and will provide references from bloggers if you want. =D
If you have any questions, please contact us via twitter @uprinting.
Thanks!
Sam
Social Media Manager @ UPrinting.com
