@Randomus: The “sale” Blu-ray discs at a lot of B&M retailers around here still are $25 or $30 a piece, while the DVD sale prices are $14.99.
You are unlucky if your local B&M retailers only sale for $25. Go online, eq amazon, deepdiscount etc.
My local Costco always on sale for Blu-ray catalog titles $18.99 and new releases $23-26. DVD for $15 and up, most of them $18 and up.
The difference between DVD and Blu-ray at Costco often close to $3. What else I can say? If you can’t find good sale in your local retailer, GO ONLINE!!
