You can probably do a two-sample t-test on your data.

Using a stat calculator, I have the following:

t= -2.78
degrees of freedom = 5

Group A: Number of items= 6
28.0 31.0 42.0 48.0 50.0 53.0

Group B: Number of items= 6
29.0 30.0 45.0 55.0 56.0 58.0

Testing at .05 level of significance using a t-table, you will likely reject the null and conclude a difference in sales.

Check this result with your own calculations.

I hope this will help.
