Subscription: request within 14 days of purchase/renewal; full/partial refund criteria depend on data and Extras usage.

Dated checkout observations and their limits
Code dassago displayed a US$4.00 (10%) deduction from a US$39.99 subtotal and a US$35.99 total at Saily checkout on 2026-10-19, before login, for one China 20GB/30-day data-only plan in USD with South Korea selected as the tax country. No purchase or account-eligibility test was completed. This does not guarantee the same discount for every product, region, account, or future purchase. Check the official China plan and your own checkout.
Future credit display: After the coupon, estimated credits to be earned: +US$1.08
Earning credit for a later purchase differs from spending existing credit now. Combining existing credits with the coupon was not tested
Partial recheck under the same conditions: 2026-10-27 KST. The affiliate landing page and the logged-out order summary for one China 20GB/30-day data-only plan, USD and South Korea as the tax country again showed the same subtotal, coupon deduction, total and future credits. No purchase, logged-in eligibility or use of existing credits alongside the coupon was tested. Do not generalize this to other products, regions or accounts.
Conclusion: The 10% for dassago is an order-summary example observed on 2026-10-19 under the conditions above. Full eligibility and expiry were not found in public materials. The current Rewards Terms did not show a clause prohibiting coupon/credit combination, so neither permission nor prohibition is assumed. Check the final total and conditions for your account.
A coupon deduction on this order is different from credits expected for a future purchase. Check existing-credit use and coupon combinations in your own account checkout; this diagram does not promise stacking. Official guidance

Check the subtotal and coupon deduction, then verify the final total, currency, taxes and account conditions separately. Entering a code alone does not confirm a discount. Official guidance
