You aren’t going to use everything in that set/palette. 10 lipsticks at a steal of a price, but if you’re only going to use two of them, that’s not really worth it, is it?
Why are you trying something you had no interest in before? Just because it’s a good value or it’s on sale doesn’t mean you need it. If you weren’t interested in it at full price, is it really something to be considering?
Limited edition is here today, gone tomorrow but repeated forever. After awhile, a lot of the holiday sets and palettes start looking the same, especially by certain brands. If you can’t partake this year to meet your goals, there’s always next year, and frankly, at the rate the industry is going, spring and summer and fall are going to turn into release bonanzas anyway.
The quality isn’t always the same in holiday sets as in full-sized products. Again, even if it’s “cheaper,” is it really worth buying when the quality is lower? Why would you want a medicore or so-so product in your collection? There are so many excellent products that there’s no reason to settle for so-so!
You can dupe it. No, seriously, do you know how many dupes I pull for most products? It’s getting to be obscene. A 15-pan palette might result in adding 500+ dupes to the database. And if you can’t dupe it, maybe there’s a reason why you don’t already own something like it (e.g. doesn’t work for you, not practical, etc.). Always check our Dupe List! You can also compare two palettes to see similar shades (or even dupes).
