The Spark Pack contains 39 Sparks, paid once: $12 USD internationally or ₹840 INR for eligible India purchases. One Spark pays for one extra Ask answer, so this is about 31 US cents or ₹21.54 per answer at the listed price. India pricing requires an Indian billing address and an India-issued card.
Purchased balances add together and do not expire. Buying a pack does not start a subscription or increase your daily capacity ceiling.
After checkout, return to Membership → Sparks and refresh if the balance has not updated. Do not buy again just because a return page is slow. If the charge succeeded but credits are missing, contact billing@cofelt.com with the receipt date and amount. Never send full card details.
Purchase availability: New purchases are briefly paused. The pricing page shows the current catalog, not an available checkout. Existing balances and billing controls remain available; the app shows which actions you can use.
