Shelley...of course she is! Thats the whole point!! If she wasn't going to make money then why bother? Its a lot of trouble to sell on ebay or etsy. You have to find the product, you have to photograph it, you have to find/buy packaging, you have to list the item, you have to monitor the listing and make sure you reply promptly to email questions, you have to then email the winner of the auction, package the goods, take them to the PO...and for all that you might make a couple fo $, oh and then wait forever hoping that the buyer will leave positive feedback. So...good for the lady for finding a source for fabric that she can make a couple of bucks on.
I've had good luck both buying and selling on ebay...its one of my favorite sites..do check the description carefully and don't buy from someone if you don't feel comfortable with any of their feedback
