A_Toad is correct, the 2400 coin/Ink pack at $1.99 is a one-time offer, and disappears after it's been purchased.
You can read up about how the transition to Ink is primarily a cosmetic change for us: https://tapas.io/newsfeed/31
Beyond the cosmetic change from coins to Ink, we also made sure that we were adding more value to readers and creators when updating the new packs. Here's a side by side comparison:
In summary:
• One-time offer for 2,400 @ $1.99 (same as before)
• 800 @ $0.99 replaced with 1,600 @ $1.99 (same price as before)
• 5,000 @ $4.99 (same price as before)
• 10,400 –> 10,500 @ $9.99 (better than before)
• 22,400 –> 22,500 @ $19.99 (better than before)
• 58,000 –> 60,000 @ $49.99 (better than before)
• 120,000 @ $99.99 (removed)
