Yes that is one of my favorite tactics, and find a garden center that is slightly second steering not one of the premium ones with massive footfall. Slight second string tend to overstock and sometimes it ends with big sales...my local wyelvales is like that, decent place but not not top string. They always have and out of season sale to make room for the Christmas stuff so they put the prices down as they plan Christmas displays ( and sometimes so me good stuff appears like the WSM), it does not last long but now and again I get lucky. WSM was my best success
