Crop Chocolate is actually more than a one-deal-a-day site; they're a one-deal-at-a-time site! They host multiple offers daily, so the more you check back, the more you get! HOWEVER, that does mean that these items sell out FAST! They often have giveaways and contest on their blog.
Flowers to Flourishes has deals that usually consist of a group of related items. Shipping here is always $4.99 (USPS) and they don't post new deals on Sundays.
EDIT: They charge $4.99 shipping for kits only. They adjust their shipping daily to accomodate smaller/lighter items. It ranges from $1.99 to $3.99.
Scrapbook Moja is a new site (started in late June 2009), but they already have great deals on big ticket items (Yudu, anyone?). This family-run (Mom, Dad and FIVE kids) site doesn't post a set shipping price, but they do use USPS, so it's likely reasonable. They offer new deals everyday and sometimes post sneak previews on their blog. You can also email them requesting specific items!
EDIT: Scrapbook Moja has closed down their site and is no longer in business!
Scrapbook Steals has great deals everyday on everything a scrapbooker/card-maker/paper-lover could want. They have $5 shipping (USPS) on everything and if you're in the Salt Lake City area, you can even pick it up in person for free! They post a deal everyday and have a blog with giveaways and sample layouts!
Peachy Cheap is my favorite of these sites because they consistently have low, low prices on things I really, really want. Peachy Cheap is run by Brooke, a mom of two boys who takes pride in her frugality and hopes to share her deals with us! She posts new items everyday but Sunday, and if Saturday's item is not sold out, it rolls over onto Sunday. Shipping is based on weight and varies.
Kindred Creations is a great blog featuring deals for low, LOW prices. For the past week, everything has been under $5 INCLUDING shipping.
Breezy Design is a paper design and manufacturing company based near Salt Lake City. Their last deal was 82% off retail price.
Two Peas in a Bucket, a well-known scrapbooking supply site, has a great deal of the day section where great brands (like K & Company) go on sale for as much as 50%!
*These are not scrapbooking based, but I think they're great anyway!*
Baby Steals is owned and run by the same people who do Scrapbook Steals above. They are similiar in that you get low shipping costs, high discounts and brand-name products; the difference is that instead of ribbon, die-cuts and paper, we're talking slings, sippy cups and teething rings. But still great deals!
Hip Green Deals is a great site started by a mom who wanted to combine her burgeoning need to be eco-friendly with her growing realization that "mom" is not synonymous with "frumpy." So she started the site to bring us accessories that would help improve the environment and us!
I hope you guys enjoy these and please let me know if you have any other great deal-a-day sites!
