ABC247.wtf – what’s in the name?

  • ABC is for that fundamental unit of behavior: the relationship of Antecedent-Behavior-Consequence. Also, we strive to provide a shopping experience as easy as ABC!
  • 24/7 is for behavior always going on and always being of interest to us – 24 hrs a day, 7 days a week. Also, the webshop is always open!
  • WTF is for What’s The Function – if you read it as something else that’s totally up to you :-).
