Maggie, the owner of Really Good Vintage, writes a weekly eponymous newsletter on Substack.

This newsletter is completely separate from the regular shop and shares finds from other sellers around the web. Occasionally there will be shop updates, but the initial intent of this newsletter remains the same (though this ethos has been extended to the irl RGV shop, too): to help people shop highly stylish vintage without breaking the bank.

There are two tiers to this newsletter: a paid subscription which gives you access to every newsletter; and a free subscription that allows access to the last newsletter of each month.
