First part of the question: waiting for the compost delivery won't hurt the Weeping Siberian Spruce. It's got a very slow growth rate (6-10" per year) so it won't get much more potbound than it is now. Wrap the black nursery pot with something white, so the sun doesn't overheat it, and keep it well watered. You say the soil doesn't retain moisture. Does than mean it drains quickly, or that it runs off on the surface? Dig a hole and fill it half way with water. Time how long it takes to drain. If it drains quickly, then use the compost to amend the backfill, but don't include any peat moss. This tree likes moist well-drained soil. The existing soil, mixed with compost will hold enough moisture to satisfy it, and as long as it drains quickly, the tree should be happy. Since you'll be installing the tree several weeks after using the RoundUp, it won't be a concern. It'll all be gone (probably already is).

With a 42" vanity, you'll have room for a basket next to the toilet. The toilet itself isn't 33" wide; that's just the clearance needed for a person to be comfortable. A scale in the guest bath? It reminds me of the Hitchhiker's Guide to the Galaxy, particularly this: The fabulously beautiful planet Bethselamin is now so worried about the cumulative erosion by ten billion visiting tourists a year that any net imbalance between the amount you eat and the amount you excrete whilst on the planet is surgically removed from your body weight when you leave: so every time you go to the lavatory there it is vitally important to get a receipt.

I have an LG bottom freezer in my utility room and one of the things I was so excited about was having the ice maker in it (last fridge had an icemaker that died long before it went into the utility room, so we never put in a connection). We have 2 teen boys and they are both in marching band. In addition to regular ice for drinks for the 4 of us plus when we have family get togethers (6,10 to 16 people most often), the boys fill gallon jugs with ice and then water for their marching practices and performances 5-6 dyas a week. Our main fridge kept up with one, but with our younger son moving up to high school this year, I wondered if we would ever have ice. The LG has a super ice setting and after we first hooked it up, I was amazed at how quickly it started making ice. Ours is not FD. The utility room is so narrow that the door shelves would be right in your face and even the smaller door would be something to have to get around. I'm sure the ice maker they use is the same though. LG did have a problem with one FD model a while back -- the interior lights not turning off. It seems they have that addressed and have switched to LED lights that are more energy efficient and will stay cooler if they ever should fail to turn off when the doors are closed. I read one comment from someone who didn't like the blueish light, but it wouldn't bother me, especially once you have food in it.

As others have pointed out, if the model number is exactly the same then it is the same item. But I will point out that the actual appliance itself is just part of the purchase. In comparing prices between appliance dealers and big-box stores, if you haven't already done so, you've got to consider the cost of delivery/installation/removal of the old appliance/etc. as well as any bargaining you can do at point of sale (discounts, freebies thrown in, etc.). I say this as someone who has purchased appliances at both big-box stores and independent appliance dealers (and, who, for what it's worth, has not found the prices all that different).
