All of those suggestions are good ones. I'll add another that I think is more important though:
Learn the zones you travel through. I know this is harder/rarer nowadays then it used to be. I've been playing since before Kunark, so to me, traveling across multiple zones, without any sort of map, just comes second nature. That's how we all did it back then. You simply learned to navigate in the zones by the landmarks around you (just like you do in RL).
If you take the time to do that, instead of just rushing through one area to get to another, you'll *know* where you died. You'll also know exactly how to get back to where you died. If you are soloing, you should maybe make a point of only going to places you can get to *solo*. I play a paladin, and have no invis spell. In 4+ years of playing, I have *never* not been able to just run naked to pick up my corpse. I have also *never* needed a bone wand to help find my corpse. If I need an invis or a levitate to get where my corpse is, it's because I was with a group when I died, and presumably someone has an invis and a levitate they can cast on me.
Not that those other suggestions aren't good ones, but if you're on a budget at all, maybe consider just using your own wits and skill to avoid needing any of it in the first place. Hunt in areas you know you can get to naked. It's just not that hard. If you can get to someplace solo without agroing anything along the way while fully armored and buffed, you can do it while totally naked. I do have spare armor and weapons in my bank, but mainly because it's old no-drop stuff. I don't keep a gate potion in my bank (why? I have one on me, and presumably I'm not going to gate while CRing until I get my corpse). Invis potions, and sows, and EBs, and levs are easy enough to get wherever you are bound. Take some time and learn which vendors sell potions you need in places like PoK (hint, look in one of the buildings near the PoT stone).
Know your limitations. Know where you can get to on your own. Learn the routes you take to get from place to place. Learn the zones you are hunting in. Learn to be able to simply look around in a zone and know where you are. The vast majority of the time when you die, it's at a "known location". You traveled to a specific spot in a zone to hunt, and died. You should be able to get back to that spot. Dying while traveling is usually the only exception, but you should be paying attention to where you are going and how you got there well enough so that you can find your way there if you die.
One last thing. If you agro something in an area you are unfamiliar with, and would be difficult to get back to (indoor zones with narrow halls typically), do not run randomly around trying to get away. Odds are that you'll just agro more mobs and end up dying somewhere where you are totally lost. That's how most people lose their corpses (and need stuff like bone chipped wands or coffins). Once again: Learn the area you are in. Learn the route you took in, and know the route you need to take to get out. If you don't know exactly how to get to the nearest zoneline, don't bother running if you get in over your head. Deaths are pretty easy to recover from if you just avoid making really bad mistakes that get your corpse lost.
