I tried it for the first time and it seems to work pretty well. I had won one of those materials coupons on a spin and opted to use it.
It allowed me to pick my order up from a Jo Ann’s in a nearby city so no shipping charges. I got some Lion Brand Mandala yarn.

Oo thsts great!
I used e the other week for some items not sold in the locations near me (Darn Good Yarn Journeys Sport Weight Silk, some clearance dk weights for amigurumi, some Lion Brand Fleece yarn that a Mister Rogers Neighborhood pattern called for, and then saw the Sirdar knit and crochet boxes kits were half price and one pair should make a great crochet mandala style blanket! Plus the needles for my machine that meri going out of stock locally…. Nice restock, good discount, a splurge, and some that i needed for specific patterns, and earned free shipping!
Thanks for sharing! 
We’re working super hard to keep a range of amazing products and to provide exclusive coupons. Can’t wait to see what you’ll do with the new yarn
