Rough rip guide

Booster box: $1,459.59 (36 packs, about $40.54 a pack). The 10 Chase Index cards cost $331.89 as singles, 0.2× that price; the full master set costs $429.66, 0.3×.

A rough guide, not an expected value: it doesn't factor in pull rates, the odds of hitting any chase card, or the value of the rest of the cards you'd pull. Buying singles is usually the cheaper way to get one specific card.
