Mentos The Chewy Mint Candy - Mint Flavor 1.32oz Rolls - 15 Rolls

Is this 100 single rolls of mentos or pieces?

Are the fruit ones the limited edition say hello like the picture or are they just regular fruit?

The price for this jumps up and down like crazy. I love these and constantly order them... Why is it suddenly $7 dollars higher in price at times?

The grape says 12 count pack of 1, does that mean just one roll or the box of 12 rolls?
