Traveling cosmetics case

Gently used to store doll clothes In excellent condition items are marked down on Friday nd Sunday hoping likers/buyers take advantage of 1) the mark down nd 2) the discounted shipping, which is when I shop on PM, But what I find is buyers wait for the item to be marked under 9 nd then pay full shipping price. Im perplexed, I don’t get it. Shop wisely nd thoughtfuly TY😎 Items marked too low may get relisted
