Know what you’re buying.
These purchase details apply to the Blackout Survival downloads and bundle. They are separate one-time purchases and do not start an Overdue Founder membership or subscription.
Products and compatibility
90-Day Supply Gap Calculator — $9.99 USD. One editable .xlsx workbook with household settings, 24 supply rows, gap calculations and a prioritized shopping list. Use a desktop spreadsheet application that supports Excel workbooks. The file uses formulas and contains no macros. The planning period is adjustable. Usage quantities and prices must be entered for your household; the workbook does not supply a complete emergency plan.
Blackout Kids Activity Vault — $9.99 USD. One 240-page PDF with 400 new numbered activities for ages 4–12 and families, plus the original puzzles, games, rotation guide and answer keys. Read it in a PDF viewer or print selected pages on US Letter paper. A printer, paper and activity materials are not included.
Blackout Survival Bundle — $14.99 USD. One ZIP archive containing the same calculator workbook and 240-page activity PDF described above. Extract the ZIP on your device before opening the files. The bundle includes both downloads with the same household-use license.
Both products are digital files. Nothing is shipped. Prices are shown in US dollars, and Stripe shows the final total before payment. These resources support preparation and offline activities; a 90-day scenario is not a forecast of an outage.
Delivery and recovering your purchase
Payment is processed through Stripe. Once payment is confirmed, your order page provides the purchased file, and we send a download link to the email address supplied at checkout. Some payment methods take longer to confirm. Downloads remain unavailable while payment is pending.
Save a copy of your file after downloading. Use Recover a download with the checkout email if you lose your link. Keep purchase links private. For a failed download, incorrect email or missing purchase, contact support@overduefounder.com.
Household use
Your purchase permits personal use within your household, including editing the workbook and printing activity pages as often as your household needs. It does not include permission to resell the files, publish them online or distribute them to other households. Contact support for organization or classroom distribution requests.
Refunds and problems
Review the product previews, formats and compatibility before purchasing. Consistent with Overdue Founder’s refund policy, we do not offer discretionary change-of-mind refunds after digital delivery. This does not remove remedies for defective, unavailable or misdescribed content, statutory withdrawal rights, or any other rights required by applicable law. Downloading a file does not automatically waive those rights.
We will correct verified duplicate or incorrect charges. If your file does not arrive or work as described, email support with your checkout email, transaction date and a short description so we can resolve the issue. Where a refund is due, it is returned to the original payment method unless applicable law requires otherwise. Do not email full card details or passwords.
Purchase information and privacy
We retain the order, product, payment status and checkout email to deliver files, recover purchases, provide support and meet applicable recordkeeping requirements. Stripe processes your payment details. Resend delivers purchase and recovery emails. Files and order records are hosted using the same Sites and Cloudflare infrastructure as Overdue Founder. Card numbers are not stored by this shop.
For privacy requests, email support. Our Privacy Policy explains the wider service, providers and your available rights. Our Terms and Refund Policy apply where relevant; these product-specific details describe the one-time downloads rather than recurring memberships.
