Boards using non-tier-1 original flash chips (including Longsys and other minor/unbranded manufacturers) are settled at 50% of the standard price for the same capacity. Judged by chip silkscreen brand, verified by warehouse teardown.
Stacking rule: If a board qualifies for multiple discounts simultaneously (e.g. cover board + non-tier-1 flash), only the lowest discount applies — discounts do not stack.

Real feedback from long-term suppliers across multiple countries.
"Delai's team came to our warehouse in Dhaka for on-site inspection. Payment was settled in full the same day. We've been working together for over 2 years — reliable, honest, and always fair on pricing."
"We ship from Buenos Aires to their Hong Kong warehouse via sea freight. Joe reconfirms the price before every shipment locks, and payment arrives within days after inspection. Their transparent pricing is exactly why we switched from our previous buyer."
"After trying several buyers across Africa, Delai offered the best prices for our UMCP boards. Western Union payment arrived same day. Their chip lookup tool helped us sort inventory before shipping from Maputo — saved us a lot of time."
"We're based in Ho Chi Minh City and ship directly to their Shenzhen warehouse — delivery takes just a few days, inspection completed same day. The cover board discount rules were clearly explained before our first shipment. Very professional team, highly recommended."
