HOW I SHIP: I am also a collector, and post all media in the same way I would want my purchase sent to me. I secure the disc with a scrap of bubble wrap, shrinkwrap the case to prevent scuffing, then send it firmly secured in a box with four sides of soft fill.
DISCOUNTS: I typically reprice early in the month. Follow my store for occasional coupons, and place items on your watch list for bonus offers that stack with current discounts.
