TJ Maxx and Marshalls stores have been known from time to time to have some odd markdowns – at times clearancing some items, but leaving others (of the exact same SKU#) at full price.
Forum member darthapathy also recently came across some sporadic markdowns at his local TJ Maxx.
So keep your eyes peeled when at these discount stores – you never know what you may come across, or if it might be marked down cheaper than you think.
