After having success earlier this week loading my Serve card at Rite Aid, I tried to load a Bluebird card there using the same procedure. No luck. It generated an error message that the manager had to clear (not something I was thrilled about, but at least they didn't think I was a crook or anything). I then used the same Vanilla gift card to load my Serve with no problem.
If you have a convenient Rite Aid, and don't have convenient access to a regularly functioning WM Kate machine, this is a game changer IMO. It is just so much faster, easier and pleasant to load at Rite Aid over waiting in line at Walmart, and the ability to also load Vanillas (which tend to be a bit cheaper and easier to buy) is an added bonus.
I currently manage 2 BBs and 1 Serve (which is enough MS for me!), and I think I'll convert at least one of those BBs to Serve. Is there any reason not to?
