I usually use cheap honey to make meads while I am working on a recipe (until I get the recipe right then I splash out for the good stuff). It won't be 100% honey if it's that cheap and it doesn't get the best result but if you are careful you can make a decent fruited (melomel) or spiced (metheglin) mead (or other meads with additional ingredients). I wouldn't go for a traditional mead where the whole character is based on the honey though, if you want to do that, go for a good one. I also wouldn't boil as the little aroma a cheap honey has will be evaporated by even a quick boil.
The key is the yeast and fermentation. Don't use normal beer yeast, I have never had any luck as those yeasts don't like the lack of nutrients (particularly US04 which throws so much sulphur that the whole house stinks!). The best I have found is Mangrove Jack's M05 which is pretty good for all types of mead. Use Yeast nutrient every other day and de-gas on alternate days following a good staggered nutrient program. The homebrewers association has a good article:
Improve Your Mead with Staggered Nutrient Additions.
I have also used wine yeast to some success but try to get the mangrove jack if you can. Lalvin D47 was the best wine yeast I used and lalvin k1-v1116 and Lalvin EC-1118 Champagne Yeast if you can't find anything else. Of course, all yeast will process the sugar so "will work" but I have really struggled with anything else (but maybe that's just me). As a last resort US05 (NOT US04!) has worked on a lower alcohol mead, but it does struggle. I have tried Belgium yeasts as well but they seem to produce a lot of off aromas and heavier alcohols.
Making mead is great as it is so quick on brew day but it does need more attention during the fermentation.
Good luck and let us know how it goes.
