Well, it depends...
What sizes you use and where you live can affect shipping costs with those that don’t use flat rate shipping.
My first pick is/was Big Cheese (Texas), who uses flat rate shipping. But in the last two years they were out of stock on the sizes I needed.
Then I went to Perfect Prey (Florida).
Then Cold Blooded Cafe came along with great pricing. But they increased their prices on my last order to be the same or a tad cheaper on some rats as Perfect Prey.
Now Big Cheese and Perfect Prey have the best packaging, vacuum sealed.
I live in Texas, and freight is cheaper with CBC, so that works out for me price wise.
