I've seen XP-2 in Boots a few weeks ago, it's not a shop I visit very often.
There's too many sticky threads and you'd constantly need to recompile as films change,disappear, re-emerge (like Agfa) etc. Not all films are available (or easily available) in all markets Kodak's very poor in this respect while Ilford, Fuji and Foma are very good.
If you want to know what films are available just check a good supplier, Silverprint in the UK, B&H or Freestyle in the US or the biggest suppliers in your own country.
It might surprise some that Ilford colour films were available in Turkey, (15 months ago) however the are rebadged and sold through the Ilford importer in Istanbul so lists can be misleading as well.
