() Iranian diplomats could soon be banned from Costco and Sam’s Club unless they receive permission to enter from the State Department.

According to The Associated Press, Iranian diplomats are partial to shopping at the warehouse stores due to the ability to purchase in bulk at low prices, including items that are much more expensive or hard to find in Iran.

The discussion of a ban comes ahead of the Sept. 22 opening of the U.N. General Assembly in New York City.

The proposal was found in an internal State Department memo obtained by the Associated Press.

It was not immediately clear if or when the proposed shopping ban for Iran would take effect, but the memo said the State Department also was looking at drafting rules that would allow it to impose terms and conditions on memberships in wholesale clubs by all foreign diplomats in the U.S.

The Trump administration has already denied visas for Palestinian leader Mahmoud Abbas and his large delegation, and is considering travel restrictions on delegates from Sudan, Zimbabwe and Brazil.
