Kits and Bundles

What's the difference between a kit and a bundle?  Kits include the pattern and yarn, and bundles include only the yarn.  Patterns for bundles must be purchased separately.  In general, the reason this difference exists is mainly due to pattern access - Ravelry restricts in-store purchases to in-person at brick and mortar stores only, so we can't sell you a pattern online unless we have a physical copy.
