I will NEVER PURCHASE FROM COSCO AGAIN!!!!!   Leaves a BAD TASTE in my MOUTH I will never order from COSCO and not thrilled with WAYFAIR  for selling!!!!  I expected the "open carton" contents to have been inspected and QC'd before putting back out for sale:
   1.  The Deck Box is inferior quality materials to begin with.  The lid warped after the first day.
   2.  The glue was loose on the lid upon arrival and finish surface did not adhere to structure.  There is no over-hang from lid to box, and especially after warping, no seal to keep dust and insects out.
   3.  There were loose screws in the carton, leaving me to scratch my head!!!
   4.  The parts were not labeled so I reversed the end pieces, and discovered too late to correct as they were snapped into the bottom piece and couldn't release.
   5.  OVERALL QUALITY IS JUNK.  

NO STARS from me.
