I've ordered from Gayle frequently. I don't expect the fastest turn around, but I've always gotten my product. Several times things have been backordered and other than the note on the original packing slip I don't think I got any other notice. On one occasion, the product took a couple months to come in - but that was a couple years ago. Everything has been much quicker since then.
How long has it been since you emailed her? I believe she has another job & does this "on the side" so to speak, because she mentioned one time about not getting to check on something until she got there after midnight.
The times recently that I've had reason to email her I got a response in as short as a few hours or as long as a week, but she explained she'd had to go out of town suddenly on that occasion.
I like Gayle a lot & have no hesitation to place an order with her or recommend her site to someone else. However, I always make sure to tell people her turn-around isn't the fastest & you probably don't want to order from her for a swap.
