I split up where I get my supplies from.
I get test strips from Kroger, and everything else from Wal*Mart.
Doc gave me 3 different kinds of insulin to try. Novolog, Apidra (fastest acting) and Levemir.
My last 2 a1c's were 5.3 and 5.2 .5.3 without insulin, 5.2 with insulin (but high summertime spikes though).
It's all the testing that is the expensive part.
