Were eBay gift cards discontinued?

I like to use eBay gift cards for transactions on eBay; however, when I recently looked for gift cards at local stores, no one had them. Not at any grocery stores, not at Walmart, not at Staples, not at Kmart, nowhere. I fear that these stores will never order eBay gift cards again now that they're out of them, because they all seemed to lose them at the same time. But, when I Google searched if anything had happened to them, I found nothing. If I can't find more, my eBay shopping will be done because I hate using my credit card online. eBay still has their Gift Cards FAQ online, and if they were discontinued, they probably would have removed them from their website to avoid confusion. Does anyone know if there's a shortage, or were they really discontinued?
