You probably know Billy the famous IKEA Storage system. In my flat i have five bookcases in silver plus two BENNO CD-Towers. Unfortunately IKEA decided to stop producing the silver ones and now you can only get them in dark grey metallic, which is ugly and too dark for my flat. When I went to IKEA SCS two months ago the height extension units were already sold out. Since then I have checked IKEA in Salzburg and Hamburg, but found no height extension units. If you know an IKEA that still sells silver height extension units, please contact me immediately.
