Can you color the price tag in orange in your design #8? We are not sure if the logo's color combination should be black-orange or navy blue-orange but can you try both alternatives?
As a final request can you also use a much more darker blue in #12 . It's hard to find the right tone by using a name such as "navy blue" or "dark blue". It can be the tone between RGB (0,0,60) and RGB(0,0,80), which you find the best for that logo.
