I don't sell yet, however I was a huge yankee tart buyer before I started making my own stuff.
I loved buying them individually...and would buy several different scents at a time. I like variety. I actually like the option of single tarts for those of us who like to switch the scent up alot.
I believe I was paying 1.49 a tart? Maybe more? Yankee online is showing 1.00 per tart. I know I paid more than that when I was buying them.
