Stacking help, please!

[Chantel]

I'm still new to stacking, so I need a little help Stupid questions may lie ahead, so I apologize in advance!

#1,
Old spice deodorant is on sale at LD for 2.99. I have the following coupons:
Save $1.00 WUB1 old spice product
Free bodywash WUB1 old spice deodorant
Save $3.00 WUB2 old spice products.

How would I go about doing this to get both products free? Does a free item with purchase count as you buying 2 items in this case? If it does, all I should need to do is give the cashier the free WUB and the $3 off any 2, and they'd ring up as free, plus tax? Am I able to use an item I'm getting free as the second of the 2 required to get $3 off? I figure I should be able to, because I still have 2 old spice products in my transaction.


#2,
(planning to do this at WM or something, LD doesn't have the correct size)
I have 2 PG coupons, one $5 WUB 2 and a $2 on one olay ribbons or quench.

I plan to buy 2 ribbons, on sale for no more than $4 each.
$8.00 - $5 wub2 = 3 - $2 on one. I figure the $5 should take care of 1 and make it free, the overage ($1) will leak onto the next olay, which I will have $2 off of, and I should get it for no more than a dollar and change.

Is this kind of "stacking" allowed at walmart/rcss/zellers etc, in your experience? Since one coupon applies to more than one product I'm unsure, but I think it's safe to "stick" it to one product and "stick" the $2 off onto the other.

#3,
Similar to question 1. Hypothetical situation here, because I don't have the coupons that I thought I did. As far as I am aware, the third coupon does not exist.

I buy a scrubbing bubbles power sprayer starter for 6.99 and I have $5 off. $2 total. I have a "buy SBPSS get refill free" coupon. If I have a third coupon, buy 1 refill get a second free, do I get 2 free refills?

Is this doable, at LD? Am I able to get a freebie here and use it towards another freebie, if I have the coupons for it?

#4,
LD's flyer this week has a B1G1 free toothbrush. It says "buy 1 at 2.99", is this a warning that means "pay full price/no coupons, or no freebie"? I doubt that it is, but I don't want to go in there bouncing off the walls again to just be disappointed, I'm on the hunt for stocking stuffers!

#5,

The new PG gift set coupons...
Does the price have to be over $10, on sale or not? I've seen some similar ones on sale for 9.95 but regular somewhere over $12, so I don't know if they'd count on those or not.

#6,
When stacking CG at LD, is it

2 items + 3.00 + 1.00 + 1.00
or is it
2 items + 3.00 + 3.00 + 1.00 + 1.00?

Since you're still buying 2 items, are you allowed to use 2 3.00 offs with the same barcode, one on each?

Thank you so much, in advance, without SCers I couldn't get awesome deals like I do
