A Walmart price leak shows what will be the on-contract T-Mobile price of Lumia 810. Good news is, it will just go for $100 on-contract. Usually Walmart prices are less than that quoted by Carriers, but in beginning of product release it can be same or pretty close to what T-Mobile is going to price Lumia 810 on-contract. Anyways, $100 for Lumia 810 is very competitive and it offers strong hardware specs and features like Carl-Zeiss 8MP camera, 1.2 MP HD FFC, Wireless charging, NFC, 1.5 GHz Dual core processor, 1 GB RAM and beautiful design as major draws.

Thanks Adnan for the Tip!! Cheers.
