You can only buy indoor shoes in batches of 10. Formal shoes and running shoes can be bought in batches of 5.
Alright I have corrected it
In your response, you are buying 15 pairs of indoor shoes. You can only buy indoor shoes in batches of 10. Therefore, you could buy 0, 10, 20, 30, 40 etc.. You can't buy 15, that would be 1 1/2 batches.
I have done the correction sir
