Met with the 'horse' this afternoon,
so here it is from the horses mouth.
Totally seasonal......stores are allocated a certain amount
based on previous sales. IN THE SPRING, when all the normal people
are set to sprucing up the yard. When it's gone, it's gone.
You MIGHT be able to special order, but the cost would floor you.
All of those items are shipped direct from the supplier,
do not go through the distribution centers,
and you would probably have to pay for a pallet shipped from
wherever (no matter how many on pallet,) plus freight.
Just Common Sense......
err....I'm not a Doctor, but I'll take a LOOK ! !
