I want to stock a roadside magic shop, whose owner has been murdered, with some stuff that might help my spellcasters, a druid and a wizard, cast up to level 4 spells.
I know that gems are pretty important, but they are already gone. So, what else can I put in there which they might benefit from later down the line?
Taken from this this list. I found the link from this thread on Reddit.

| Summon Beast | Hollow gilded acorn | 200 gp |
| Summon Fey | Gilded flower | 300 gp |
| Land Circle | Incense and a sacrifical offering | 25 gp |
| Stoneskin | Diamond dust | 100 gp |
| Summon Elemental | Crystal vial + common components | 400 gp |
Wizard
| Spell Name | Component | Cost |
|---|---|---|
| Chromatic Orb | Single diamond | 50 gp |
| Find Familiar | Charcoal, incense, herbs | 10 gp |
| Identify | Pearl | 100 gp |
| Illusory Script | Lead-based ink | 10 gp |
| Protection from Evil and Good | Holy Water or Powdered Iron and Silver | (5cp-25gp)***(1gp suggested) |
| Snare | Rope, 25ft | 5gp (silk) or 5sp (hempen) |
| Arcane Lock | Gold dust | 25 gp |

| Summon Shadowspawn | Tears in a crystal vial | 300 gp |
| Summon Undead | Gilded skull | 300 gp |
| L's Secret Chest | Exquisite chest + replica | 5000gp + 50gp |
| Stoneskin | Diamond dust | 100 gp |
| Summon Aberration | Platinum inlaid vial w/ pickled tentacle and eyeball | 400 gp |
| Summon Construct | Ornate stone and metal lockbox | 400 gp |
| Summon Elemental | Crystal vial + common components | 400 gp |
The catch being, you'd need to know what spells your casters might be interested in. I'd suggest diamond dust as stoneskin is very useful. Holy water also pops up for a few spells.
Also, keep in mind that the players might just sell whatever you provide for them. Especially anything worth over 100 GP.
Indirectly, any valuable spell component can help your wizard and druid cast spells, because it can be re-sold or traded for components they can use.
Components in common demand would need to be affordable by lower level, less affluent casters. Let's say anything up to 100 gp. Common components listed here are for spells from the Players Handbook, as many of the spells from the various extension books appear more unusual and exotic, and their availablity in the game is optional. (You can ignore the pearl and diamond if these have been taken).
In addition, a substance that would be of high value for a wizard and should be available in any magic shop catering to them is the magical ink that wizards need for penning their spells, worth 50 gp per spell level.
Aside from these, you also could have spell books (50 gp), other books (25 gp) on arcane subjects, component pouches (25 gp), and spell foci (1 to 20 gp) on the shelves. You could consider useful alchemical substances, like acid (25 gp) or alchemists fire (50 gp), and tools of the trade like parchement(1 sp), paper (2sp), scroll cases (1gp), ink (10 gp), vials (1gp), silk rope (10 gp, for rope trick), and robes (1gp).
Lastly, although this is more costly and would be less common, you could consider a crystal ball (1,000 gp) as the high end item on display, because it is such an archetypical trapping for wizards.
