‘The Price or Selected Model Has Changed’ and ‘That Tier No Longer Exists’: What They Mean

Quick answer: ‘The price or selected model has changed’ comes from the few places that promise you a price before charging: an ad’s one-price and a remake’s quote. If the current price is higher than the one you confirmed, the click is refused and the new price is shown; nothing is charged until you confirm it. A card or PayPal membership upgrade works the same way with its own confirmation. Sheets, storyboards and clips are different: they are charged the price at the moment you click, with no second check, so a rate or allowance that changed while the page was open changes the charge. ‘The selected video tier no longer exists’ means the tier you picked was retired: the click is refused, nothing is charged, and you pick another tier.

Start an ad or a remake, leave the page open for a while, then confirm: if the price moved in the meantime, you are shown the new number before anything is charged.

Where a price is promised in advance

Ad one-price: fixed when you start; before each paid stage the site checks the current price, and if a stage would now cost more the ad stops and asks. Remake quote: shown before the read and checked when you confirm. Membership upgrade by card or PayPal: the amount is shown first, and the charge is refused if it changed since you saw it. In each case you see the new number and decide. Subscribe, Upgrade, Cancel.

The episode timeline: every segment as a card with its thumbnail and duration — Most buttons charge the price at the moment you click; only a few flows promise a price and check it before charging.

Everything else is priced at the click

A sheet, a storyboard or a segment holds the price computed when you press the button. What can move that price while a page sits open: a tier’s rate adjusted, the account’s free sheets or the first project’s free storyboard used up elsewhere, a longer segment. Refresh the page before a large batch if it has been open for a long time. Why Video Costs More.

Tier no longer exists

Model tiers come and go as providers change. A segment submitted on a retired tier is refused with this message and nothing is charged; the selector no longer lists that tier. Refresh, pick another tier in the model selector in the editor’s top bar and generate again. The segment keeps its text and versions. Which Model Is Best.

What to do

For an ad or a remake, read the new number and confirm if you still want it. For a retired tier, pick another. For a surprise on an ordinary generation, check your credit history: each row shows what was held.

FAQ

Was I charged the old price or the new?

Neither; the click was refused. The next confirmation charges the price shown then.

Does a normal generate button check the price again?

No. It charges the price at the moment you click.

Can I keep the old price?

No. For an ad or remake you confirm the new one or stop.

The tier I liked is gone; will it come back?

Tiers follow provider availability; the selector shows what is offered now.

Was anything charged when the tier was gone?

No. The request was refused before anything was held.

Confirm the new number, or pick a tier

Where a price was promised, a higher one is never charged without asking.
