Is eBay still in fashion? Maybe?
Maybe not. But my husband was reminded of the wonders of bargain shopping when he discovered he could purchase his favorite guitar strings on eBay for less than half the price of retail. A few years ago he was busy selling things on eBay--mostly rare and/or valuable CDs. He stopped it when he realised how expensive it was to sell there.
Digression over. I recommend you search on eBay for supplies you need. You may find them at a discount, and you just might be supporting an independent business owner. It's worth a shot.
