Here are your choices:
1. Never receive the lot since the seller cannot be compelled to send it.
2. Make a complaint to
ebay about seller not following through per
ebay rules. The seller will be punished by
ebay (higher fees and perhaps other restrictions). Seller still has no incentive to send the lot now as the damage from
ebay has been done and is irreversible.
3. Plan not to do business with the seller ever again since the seller will likely black list you and block you from future listings.
4. Do none of the above and get to bid in the future.
5. gently advise the seller there is the RESERVE function on listings.

New message from: tropicalcollectibles (6,144GREEN_STAR Star)
Dear valued customer
I have made a terrible error on the price with a typo. It should have read 149.98 and not 14.98. I am the clerk that puts in the data and my boss is very upset. He said for your inconvenience he can offer this to you at a 10% discount, but we have to decline this purchase.
I apologize. Thanks for your understanding.

I believe the message came AFTER the sale was cancelled.
Now this seller has feed back of 6122 with over 9,200 items sold. The seller made a mistake but to offer a tiny discount for correcting their error is a slap in the face. Now I have never purchased from this seller and am evaluating if I ever want to make a future purchase before I take any action.
In reality, my plan was purchase and pay then check in with the seller 3-8-2023 to see if that was the intended price for the item or if an error. then discuss action. If a known seller, as a favor, I would buy it, then ask if they want to sell it to me or relist the item at the correct price.
Last comment, "binding contract" is a two way street, sellers should not get to play fast and loose when buyer have their feet held to the fire. Human error happens but the correction should be a negotiation.
