hi, i would like to buy High Quality Anti Glare/Anti Finger Screen Protector, High Quality Silicon Case & High Quality Flip Pouch Case, if i bought all 3 together, can i have special discount on the postage fee? or i still have to pay the postage fee for every item i purchase?

I am using BlackBerry Curve 8520, is it the 3 products above got ready stock for BB Curve 8520?

hope to get your reply as soon, thank you.
