Maybe my Green Grocer guide can help, although it's outdated and now many of the parts are indeed super tough to find:
Thanks... Actually, I've already read it (but strangely, elsewhere I think... maybe reddit).
It's a bit out of date, but not so much. And there's not so many parts that are really expensive should you avoid sand green and switch the door borders and water taps (it's far cheaper without a hole you can't see anyway) :
- the sand yellow 1x6 arches is, by far, my main issue (only 2, but often over 5$)
- the light bluish 1x8 (needs 29 at ~50c) is the second problem, I may use smaller ones
- the light bluish 1x16 (only 1, ~1$)
- the white 1x2x2 wall elements (2 at 8$, but I'm investigating a cheap alternative with just - the black poles (needs 2, ~1$)
- the dark red inverted slope 1x2x3 (4 at 4+$), I may switch the color although I like it :/
- the dark green 2x2 (needs only 3 at ~50c, and those are invisible in the tower ceiling)
- the kitten (at 3$)
- the train windows (4 at 8+$), which can be switched for 1x2x3 windows
additional borders... I don't know yet where they are in the green grocer)
- the black staircases
- the light street pole
- the viking pieces (rare, at 3+$)
- the blue arches (but will switch color)
plus a couple dozen .50 - 3$ large plates and the 8$ baseplates
Now, even if everything else is not really expensive, I may have issues with smaller orders and shipping costs :/
Updated assistance: You can use regular 2x3 windows instead of the train windows
That was my current plan (although I think I may have 4 of those... I've at least 2 from the old space monorail for example).
In fact, I've snatched a spare Pet Shop, and there's plently of useful pieces for a "Blue Grocer". Including the windows, the light pole (which is really expensive now), black staircase, plently of sand blue including ones with grooves and base plates, beside a bunch of other common and less expensive parts.
In case the sand green really kills your budget, there are many other colours that the Green Grocer looks awesome in. Check this thread:
Already seened it... I'll most probably use sand blue, I really like it in this color, even if there's already the pet shop in sand blue.
As for the details, the blue curved pieces for the awning are rare since that asshole Jamie Berard used parts that are also used for Grand Carousel (which is entirely made from rare pieces). You could look for another colour for them.
Will do, especially since blue on sand blue may not be the best association. I may also switch the curtains colors (dark red is expensive).
I love the design, but I don't value minor tweaks or alternate colors several dozen $... I'll switch those later if they drop in price.
