fishorama's advice is right on !
Small 1" to 2" discus are just babies, with their immune systems only just beginning to develop, and are very prone to all types of health issues, unless kept in pristine water quality and conditions, in a bare-bottom tank, with large daily water changes, and 5-6 feedings a day.
If they don't receive that kind of care & attention, it's highly likely they either won't survive very long, or their growth will be stunted, or a combination of both.
That's why they're inexpensive when that young, and larger discus are much more costly, due to the time & effort it takes to raise them properly.
Caring for young discus like that generally requires a good deal of prior experience with growing out discus, so it can be fairly said that it's false economy to buy fish that size if you're a novice at keeping discus.
Better to pay $200. for 4 or 5 discus of say 3.0"-3.5" in size and keep them alive & thriving, than to risk $100. on 6 very small discus, only to have them perish within 2 months.
Whatever you decide, fishfanman, best of luck to you, and don't hesitate to call on me if I can be of any help at any time.
