Yes, they do have some availability outside the USA, but we may not have as many models available as you do. I'll certainly consider it when the time comes, alongside considering non-Apple hardware for the first time in a decade!
My guess since they discontinued the 2015 13in pro that the "refurbs" are just the new stock they are trying to clear out. They will most likely just re-box the new units in refurb boxes. Also they are almost 25% off of list price you might want to get one before they are gone if you are on the fence.
