Costco

They have 32 microfiber 16x16 rags for 16 dollars. they also have some tire shine 4 cans for 11$

 

I got some of those towels a couple of months ago, I use them on the interior and rims and they work well. What I love best is I am not mad when they get destroyed because they are dirt cheap!!!!

 

yeah im not sure i would use them for buffing but they are great for interior and dirty place. just replaced my old ones today. they also have a 3 microfiber 2 drying towel pack for like $15. love the towels for drying and the mitts are the same as griots for half the price

 

Sam's Club MF pack is a lot better quality than the Costco ones.

 

you can use them on interior and on wheels, but I woudn't use the on paint...

 

I've used Sam's Club MF on paint w/o any issues. I'm not condoning the usage of them by any member here (haven't done the CD test), but YMMV.
