I bought this case for my new Lumia 900 from Amazon for $5.90

Amazon.com: Kay's S-Line TPU Soft Gel Case for Nokia Lumia 900 (Blue): Cell Phones & Accessories

It was pretty good for the price, so I decide to write them a nice review, only to find out that the price is dropped to $2.49

I was a little angry so I wrote this review

horrible price change

This case fits well and there is a great design for phone chain
However,price changed too much which made me to give 4stars only

Seller came back with this feedback:

Sorry for the price change. There are knock-off products listed under our product for sale because our product has no logo. Therefore, we have to sell out the inventory at a lower price, so we can relist the product with our logo.

Contact us, and we will do a price match for you.

I won't bother for the price match of $3.5, but I would like to share with you guys the good deal. If you are not familiar with Amazon shopping. You can get free shipping if you get a prime account or buy over $25 worth of products.
