Stock up or wait?

Extreme couponing has been around forever, but because of our failing economy it seems to have really become the latest fad.  Using the Internet, newspapers, and social media in general have made saving money a new hobby for a lot of families.  I myself have caught the bug and live for my Sunday paper, and watching Facebook for the latest coupons to pop up.  My biggest guilty pleasure is TLC's Extreme Couponing, its like a car accident, you hate it...but you have to look! I can't stand the clearing of shelves, its selfish. I have gone to stores and seen a great price with a coupon in had to get a deal, and its totally cleared, no rain check, no nothing..just an empty basket and wasted gas.
All most all of the shows couponers have stock piles, that they practically worship.  I have gotten several items in bulk that I find on sale at a deep discount. However, my husband would kill me if I had a stock pile. Living in military housing you have to figure out space, and if anything is getting extra space its gonna be my man's military gear. Recently Amazon.com had a special on Joy dish soap, you could get a case of 25 for $7.40.  I was so excited when it came, first thing my hubby did was grab a plastic bag and put 5 in it to take to his Mom's house. He feels that with the move coming up do we really want to pack extra dish soap?That made me wonder about the case sale on post being next week...should I skip it this year or should I stock up and move the loot with us? My biggest fear is the truck being packed like it was last time and not having room for everything. On the other had  we could end up in an extremely small town with the nearest Wal-mart being an hour away and not having anything real options on deals. Its something to think about, and I've only got a week to make up my mind.
