Hi there, Thank you for reaching out to Northwind Outfitters. Because your coat was purchased 45 days ago, it falls outside our 30-day window for a refund to your original payment method. However, for unworn items with tags returned between 30 and 60 days after delivery, we are happy to offer an exchange or a store gift card for the full purchase amount. Please let me know which option you prefer, along with your order number, and I will get the return process started for you right away. Best regards, Sam, Northwind support

Hi, Thanks for reaching out. Our return window starts on the delivery date, rather than the purchase date. If your coat was delivered within the last 30 days and is unworn with its tags attached, you’re eligible for a full refund to your original payment method. Refunds are paid within 5 business days of the return reaching our warehouse. If it was delivered 31–60 days ago, we can offer an exchange or a store gift card, but not a refund to your card. Could you confirm when your coat was delivered? Sam, Northwind support

Gemini 4 Argon and GPT-6.1 Sol on every plan
Whether the one-time free trial reaches each model, then each paid plan's messages on it.
| Plan | Price | Gemini 4 Argon | GPT-6.1 Sol |
|---|---|---|---|
| Free | $0 | Not in the trial | Not in the trial |
| Plus | $10 a month | Up to 31 a month | Up to 62 a month |
| Pro | $20 a month | Up to 62 a month | Up to 125 a month |
| Max | $50 a month | Up to 200 a month | Up to 400 a month |
| Ultra | $100 a month | Up to 450 a month | Up to 900 a month |
| Studio | $200 a month | Up to 1,000 a month | Up to 2,000 a month |
Prices don't include tax, which is added where it applies and shown before you pay. A paid plan's month is one allowance shared by every model, so each monthly count is the most you get if all of it goes to that model. It renews each billing period; everyday models refill daily at 00:00 UTC. Long chats count more per reply. How pricing works.
Every limit is published. Paid plans also have a monthly fair-use limit on AI cost: Plus $3.75, Pro $7.50, Max $20, Ultra $42, Studio $85. Using every message on your plan at typical sizes stays under it; very large messages and heavy research use it faster. Every limit, explained.
