Over the past year or so I've noticed that most local supermarket chains are now selling imported tea from the UK and Ireland - brands such as PG Tips, Lyons, Barry's, and Bewley's - at not unreasonable prices. There on the shelf, right next to the Lipton and Red Rose. They are actually becoming commonplace now. While these brands might not be the pinnacle of tea drinking, they are abundantly superior to their US counterparts, so I wholeheartedly welcome this trend and hope it continues.
That being said, often there are still better deals on the Internet. I ordered some PG Tips from Amazon recently and it averaged about $3.50 per 250 grams. Shipping was free if the order exceeded $50, as I recall.
