"Burns would be turning in his grave."

Two incorrect notions there - firstly he is in a Mausoleum and secondly it is highly doubtful he ever wore a kilt!

It's difficult to judge the issue without actually seeing what Lidl are offering - many of us have seen Gold Bros offerings on the other hand.

Also Lidl are unlikely to prove a long term competitor to quality kilt establishments, it's just one of their offers that are here today and gone tomorrow.
