STAPLES HP Memorex media $5 & $7 B&M closeouts(?) (not "clearance") some printer paper too

Remember the Staples 28# heavyweight printer paper that was $1.50 after unlimited rebate a couple years ago? It was not on clearance, but it was put at a low price until stock was gone and never came back -- an unannounced close-out.

Currently in Staples B&M are these deals that are not clearance, and not on a weekly or monthly promo. Any expirations given on the price tags come at the end of the year. I think these are on an unafficial B&M closeout...

These were $15...

Memorex 25pk DVD SKU 765364 $7 INSTANT

HP 25pk printable CD-R SKU 695821 $5 INSTANT

Regular $8.99...

Staples 24# 50% recycle printer paper SKU 756972 $3.99 AR (LIMIT 10 REBATES PER RECEIPT / ADDRESS)

This one is a clearance...

Reg. $149.98 HP C5580 AIO printer SKY 753746 $50.50 INSTANT

RIP

Are the "INSTANTs" the current prices? or instant discounts off of regular prices?
To reach the $xx/$yy coupon threshold, are the regular prices considered? or the discounted ones?
If regular prices, then this could be a sweet deal.
Thanks!

Thanks. It does help, if I am understanding it correctly. $7 OTD for DVDs, and $5 OTD for CDs.

Now the second part of my question. Are they ringing up at these prices, or are they ringing up $14.99 less instant discount = OTD price?
In other words, if I buy 5 x $14.99 = $74.95 + filler - $25off$75 coupon = $50 less instant discount $8x5 = $10 OTD for 5 DVD packs.
Will that work?

Or do I have to buy 11 x $7 = $77 - $25off$75 = $52 OTD for 11 DVD packs?

Either way, it's a great find.
