both centers hire contracted 'muscle' for the season. unless folks have some know how they are usually clueless.
we bought storage shed from lowe's using gift cards. went to lowe's, they were.... clueless. one person was 'knew little bit' about them. had to wait on them, they then informed me they don't carry many of the sheds in stock. i'd have to order online.
then told me i'd need to build a platform. since sheds have them, some are hollow in bottom.
oh! and the shed would be have to be putv together.
i asked if they could do it. they said, maybe. sometimes they will put together if I buy in store. but i'd still have to have a flat concrete or wood base.
several weeks later, and an entire weekend we received our order in the email. we had it shipped to the store to avoid shipping, and so they could take the 5% lowe's card discount off.
guess what? there was one person who knows how to do that. and had to wait a long time for them to do that.
then they struggled getting the gift cards to work.
oh, don't worry. we (wife) opted not to pay them to put it together. we have kids, so, it took about two full days to assemble
in short, take the time to plan it out. take your measurements and buy as big as you can.
build your platform off the ground, ensure its where it will always be. there is permanence.
I would recommend spending the extra money. Height wise you can always go taller, than deeper.
There are dozens of local wood shed builders. Who may be able to custom make one. Wish I had spent the coin for nicer one.
