In my experience, sourcing such inexpensive items locally (if you are located in a western country) is your best bet. Inexpensive, small carabiners that are of acceptable quality for your purposes are found just about everywhere in the USA (and I suspect many other western nations) at big box departments stores, hardware stores and home improvement stores.

I stopped buying such items from China because the quality is hit and miss, the shipping times are not worth the savings and recourse is not worth the hassle or expense.
