Haven’t done a “bag the bags” round-up recently, but one should be coming in the next few days. In the meantime, if you are fond of mail-in rebates, you can get the Lowepro Nova Sport 35L AW Shoulder Bag for 1-2 Pro DSLRs with Attached Lens, in the Slate Gray color scheme (not the fiery red pepper orange) for $10 after a $10 mail-in rebate. Free shipping. According to the PDF details, the rebate covers up to five units of this particular model. The mail-in rebate is a prepaid Mastercard gift card, not a cashable check. This particular rebate offer works only for purchases made at Adorama, not other retailers.
Speaking of bags, the AmazonBasics DSLR Backpack remains at $25 with a limit of three per customer (averages 4.4 out of 5 based on 4000+ customer reviews). The usual Amazon free shipping terms apply (Prime or $35+ order).
Speaking of Adorama, they have the refurbished (by Makerbot) MakerBot Replicator Desktop 3D Printer, 5th Generation, 100 microns Layer Resolution, on sale for $1500 with free shipping. Offer ends 1/17/16.
This looks like a great deal for someone on a budget who needs a larger bag. However, please permit me a quibble with the post headline. “MIR” is an ambiguous and therefore problematic acronym, one I would avoid. It’s used by many sellers to mean manufacturer’s instant rebate. That meaning is much more common in my experience than when some sellers use it to mean mail-in rebate. In most typefaces lowercase “mail” takes up about as much headline space as all-caps “MIR” and keeps things clear.
