I didn't pick anything up in Dublin - too busy with the convention and didn't see much of the town apart from the convention centre, Trinity College (I was staying in student accommodation), and the streets in between.
But I had a good find in a charity shop today - a Pentax ME with case and instructions, a Pentax-M 1.7/50, and a Pentax-M 2.8/28 with caps, case, and a booklet on Pentax lenses, all clean and working well. Got the lot for £45, I probably won't make a huge profit but it's supporting a good cause and I ought to at least break even.
Also received a job lot I bought last week, 25 used 52mm UV and skylight filters for £19 inc P&P. I like to include caps and filters with the lenses I sell as a value added thing, and I'm always running out of the most popular sizes.
