# Does Anyone Shop Sales, Groupon, Coupon, etc. Regularly?

If so, feel free to share cool deals.

My latest thing is looking into getting free advance movie screenings. Good to save $and enjoy a film before a bazillion reviews and friends/family ruin them for you with spoilers. I do Groupon when I see some nice 50%+ off restaurant deals. And, lastly, I coupon at Target. Always open to learning about new deals. 2.

(I learned about it first from Volume 1 of Feller's An Introduction to Probability Theory and its Applications. Look for "collector's problem" in the index.) (@Demystifier, given your interest in this sort of problem, it is actually something you might enjoy. As you can see from the above reference, your fellow countryman strikes again.)

Jul 27, 2017 ### Krylov Since we are on a science forum, I thought it could be interesting to approach the problem of coupon collection mathematically. In particular, using the results on the collector's problem, one may compute in certain instances whether the decision to collect coupons has positive monetary expectation. (As can be seen from the link, this depends on the number of required coupons, the expected number of trials and the price per trial.) If you don't care for that, then by all means, don't bother. It very much relates to the subject, though. 5. Jul 27, 2017 ### russ_watters ### Staff: Mentor Well that link refers to "collect and win" "coupon" contests, which sale coupons are not. Your probability of getting all available sale coupons from a particular source is 100%. 6. Jul 27, 2017 ### Krylov I did not get from the original post that the discussion was focusing specifically on sale coupons. Last edited: Jul 27, 2017 7.

I also get involved in rewards programs for services I often use. Couponing has never worked well for me. It seems the products with coupons are products I don't want. 9. Aug 2, 2017 ### vela Staff Emeritus I use ebates.com to earn cash back from some retailers, and like Greg, I'll often check retailmenot.com before placing an order online. In the past, fatwallet.com was a good place to learn of deals. I try to take advantage of deals my credit cards offer as well. If you're looking for test screening for movies, check out gofobo.com. You can buy discount movie tickets passes online at Costco.com and AAA and print them out at home. 10. Oct 13, 2017 ### WWGD I assume I assume you're familiar with extreme couponing ? I have seen people obtain 3-4 shopping cart full of merchandise for some$20 or so. I assume supermarkets are not happy to see them coming in.

As far as I know, the extreme couponing is a scam. We had a thread about it before.

Do you mean the couponers are the scammers or the scammed?

Some extreme couponers might be scammers, but some are legit. A girl from the show Extreme Couponing has a YouTube channel with her husband (His & Her Money) that I sometimes watch and they are devout Christians with very high ethics. She's talked of her experiences on the show Extreme Couponing and of how she shops nowadays.

Extreme couponing is a lot harder post-EC show, because stores, manufacturers, third parties, etc. got smart to what was going on. You can still do nice hauls, but you probably won't see people doing the crazy stuff on that show (\$1,000+ of groceries/goods for like 10 cents after all the discounts and coupons are applied).
