Indeed! Even normal items that are of excellent quality may cost 2-5 times as much as their normal variations, so those are potential ways to use gold.
And living supplements do add up - new clothes, better packs, small strongholds to keep their wealth and keep it protected.. all of these do have a price. Even adventuring equipment that gets broken or has limited use may eat into those precious gold pieces - lantern oil, torches, rations, scrolls of protection, potions, etc.
Rather than high-quality items I was thinking of high-price items like Spyglasses (1,000 gp), Medium Warhorses (225 gp), Fine Fur Cloaks (50 gp) or that old standby Silk Rope (10 gp per 50 ft.).
Masterwork grade equipment isn't included in the core 2E AD&D Player's Handbook, so I didn't want to assume it was available.
