Wow. I honestly didn't expect anyone would still do this. Do you not have good internet?
My internet is patchy, and to be honest it's more convenient to get discs. It's also mildly exciting looking forward to small packets coming in the post once or twice a week throughtout the daily drudgery of work (Rogue One is in the post today!). Once I'm done with The Wire I plan on committing myself to The Sopranos (disc by disc by disc!)
Only real issue is postal problems or bank holidays....
