Amazon and eBay are great places to find inexpensive g-strings. If you purchased some Doreanse from Amazon, then you possibly ordered the wrong size. I have ordered several of the Doreanse g-strings from Amazon and they fit me nicely and were very comfortable. There is a G_String thread in the General section with pictures and descriptions of many of my g-strings. With that said, most of my g-strings have come from eBay. There are multiple sellers on eBay that sell them. They typically are in the $15-$20 range so might be higher than you are wanting to pay. Aliexpress is another great source for g-strings, but you have to watch sizing when ordering because everything typically runs small on there. Feel free to ask any further questions here or you can send me a personal message if you prefer.
