I had this dilemma a couple of weeks ago. I found a good deal on Amazon too but I didn't get them within 2 days as promised. I would stick to ordering in bulk from a vendor in the states especially if you need them soon. Also check Walmart.com as they sell bulk wrappers. Lastly, if you are a business owner then you can become a "buyer" from CK Products. Minimum purchase is $125. Other options are etsy, ebay, usacakes.com, and cake art party store.

Are you in the US or abroad? Shipping can always be a killer. Are you looking for patterns or solid colors? I am not sure what your price point is but bulk seems to always be the better option. The place I get my liners from has 500 quantities available and a huge selection. I love the liners with a prefix of SC-; they are a good quality paper and I have had great success.
Wow! Thank you all for the great ideas! I was able to find affordable cupcake wrappers :] thank you all for the great advice!
