I got my black/pink bag from Petsmart.com. Sebastian and I love it :-) It was $19.99 and only $27.00 with shipping & tax. It only took about 4 days to get here.
Here is the link:

Everyone I have came across have thought this was just a big purse or a diaper bag (if you have a toddler/baby) and the quality is great!!
I forgot to add that it does zip up on top, I can send pics if you want.
