I just love online shopping when you can find great coupons!
One great place to find these is CouponChief - they have tons of merchant options!
I have a personalized letters for children business, and I am constantly having to shop for supplies and mostly I do that online.
When children are subscribed to my service, once a month they receive a personalized letter from me, in which I tell them about a great book and strongly encourage them to read, making sure they know that it is fun and awesome, not just a chore! The children also receive easy-to-do crafts and fun goodies.
I buy all of the crafts and most of the goodies at Oriental Trading Company, and there are some great coupons for them at CouponChief.com!
And I buy business cards, '#1 Reader' magnets, and pencils at VistaPrint.com and they have great coupons for them, also!
One time I even found a coupon for free shipping on the free business cards - so I payed $0.00 for 250 business cards - it was awesome!!
