I think we reached the point where most of the major memory card manufacturers are not using mail-in rebates, so we won't be mentioning "no rebates" anymore, since most of them don't have mail-in rebates. We will only mention mail-in rebates for memory cards that do have mail-in rebates.

For the big picture, and future checking and testing, check the Canon D-Rebel Instant Rebates page.

PLEASE NOTE: this lens goes in and out of stock like crazy. You may have to try and try and persist in order to find it in-stock!!!

UPDATE: The double-double savings appear to be DEAD.

Best Buy expired: The Tuesday deal of the day at BestBuy.com is a $100 iTunes gift card (your choice of digital delivery or plastic gift card delivered by mail) for $80. This is a 20% discount. Of photography interest, there is a variety of camera and photography related apps for the iPad, iPhone and iPod, along with photography related interactive books in the iBooks store, and audiobooks related to photography.

UPDATE: Woot-OFF continues for Day #2! It is that time of the month again, a new WOOT-OFF has began!. In parallel to the main Woot-Off, there is also a Kids Woot-OFF and a Home Woot-OFF.

Woot-OFFs typically last 48 hours, and sometimes 72 hours. This round started on Tuesday at 1am ET. Due to time and sanity constraints, we will not be following this on a play-by-play basis, so that part is a DIY adventure.

As of Wednesday 9:50am ET, the current Woot-OFF special is a 64GB Centon SDXC Class 10 card, model RC64GBSDXC, for $40 plus $5 flat shipping. Limit three per customer at this price. Shipping is $5 regardless of how many you get.

+ K30 various kits from $850 to $1200 at B&H Photo and Amazon
+ 50mm f1.8 DA for $250 at B&H Photo

UPDATE 8:42pm ET: It appears the 75-300 remains sold-out! The 75-300 instant rebates are live again as the lens is orderable again for $160, with a $100 combined purchase instant discount. This means you can add it to a qualifying DSLR kit for +$60.

Still remaining in-stock is the 55-250, with a current price of $215, and with a $150 instant rebate, it means you can add it to a qualifying DSLR kit for just +$65.

See the Canon D-Rebel Instant Rebates for the whole litany.

I have to preface this by saying I don't know if this is a new feature or a bug or some variation of the double instant savings. Typically the Canon Instant Rebates are stackable with the lenses. But now, they appear to be stackable on DSLR bodies as well. If you buy two eligible DSLR kits and one eligible lens in the same shopping cart, you get the lens discount twice instead of once! If you buy two different eligible DSLR kits and two different eligible lenses, you get the lens discount twice for each lens. You can't buy two units of the same lens and get the discount twice. The shopping cart will decrease the quantity to one. This works for any eligible DSLR kit and lens that is in-stock. Eligible as in participating in this particular Instant Rebates promotion. Currently the only eligible in-stock lens is the 55-250 (the 70-300 and 75-300 are out of stock). You can mix and match D-Rebel and 7D/60D kits for this. The participating DSLRs and lenses are the same as before, see them at the Canon D-Rebel Instant Rebates and the 7D/60D instant rebates.

We will revisit this tomorrow...
