Makeup returns

So I'm used to using a lot of the same makeup throughout the years. But of course all the important ones I have been using have been now discontinued. Example Clinique line smoothing concealer I used for 25 years. (03 Moderately Fair) they have another concealer now that's nowhere is good and I can't get the same color match. So my question is - can we even return make up that we try? i've done it at Ulta. The first time I returned something they just let me exchange it. I didn't bother returning the second one because there was nothing else comparable.

So what if I go to Walmart and I buy something like Maybelline. Do they accept returns at Walmart or similar stores if you don't like the color??? because after a while I found a great Milani concealer Retouch + Erase (01 Fair). And now they discontinued that 🙄 so now I have to go out and find another one again. ........ While we're at it please suggest a good product for someone with fair skin with dark circles under my eyes!! (i've tried color corrector products but my dry skin always makes it cakey. and then if I put more moisturizer there it just sits on top and then piles up once it dries). i've just had better luck with concealer in the past under my eyes.
