Are vendor delivery estimates actually accurate?
Honestly, the estimates are hit or miss—I'd plan for a few extra days just to be safe. For a noob question like this, I’d say don’t overthink it; most delays are just logistics. When I first got into this, the best move was to read the sticky at the top of the board, it covers everything from getting started to vendor track records. Also, if you’re prepping your own stuff, take care with the lighting setup shadows when doing the ID photo at home, that tripped me up.

Tracked my own orders against vendor estimates for a year. Here is the data and what it reveals about how to use those estimates.
My data
Tracked 12 orders across six vendors, noting the vendor's stated estimate range and the actual delivery date. Results:
The median delivery landed at the end of the stated window or slightly after. No orders were dramatically early; two were notably late.
What vendors are estimating
Vendor estimates typically cover shipping transit time only, not production time. Production can add one to three weeks before shipping even begins. When a vendor says "10 to 14 days," they often mean 10 to 14 days after the card ships, not after you place the order. Distinguishing between order-to-ship and ship-to-delivery estimates requires reading vendor FAQ carefully or asking directly.
Seasonal variation
The two late orders both occurred during summer. The two early deliveries were in January and March. Summer customs volume, staffing at sorting facilities, and carrier congestion all affect actual transit time in ways that static vendor estimates do not capture.
How to use estimates
Add production time to the shipping estimate to get a realistic order-to-delivery window. Add 30% buffer for seasonal or customs variability. Use the vendor's stated estimate as the optimistic case, not the expected case. If you need a card by a specific date, add all the buffer and then decide whether the timeline is realistic before placing the order.
The most accurate delivery timeline estimation comes from talking to people who have ordered from the same vendor recently via the same route. Forum threads where people report delivery times for a specific vendor in the past month are more useful than any estimate the vendor publishes. Recent real data beats stated estimates every time.
