Some possible usage issue:
"We strive to provide customers with great prices, and sometimes that means we limit quantity to ensure that the majority of customers have an opportunity to order products that have very low prices or a limited supply."
Is it standard English to write:
"That product has a limited supply."
We would normally say that products "are in limited supply".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
