(A) No supplier shall commit an unconscionable act or practice in connection with a consumer transaction. Such an unconscionable act or practice by a supplier violates this section whether it occurs before, during, or after the transaction.

(B) In determining whether an act or practice is unconscionable, the following circumstances shall be taken into consideration:

(1) Whether the supplier has knowingly taken advantage of the inability of the consumer reasonably to protect the consumer’s interests because of the consumer’s physical or mental infirmities, ignorance, illiteracy, or inability to understand the language of an agreement;

(2) Whether the supplier knew at the time the consumer transaction was entered into that the price was substantially in excess of the price at which similar property or services were readily obtainable in similar consumer transactions by like consumers;

(3) Whether the supplier knew at the time the consumer transaction was entered into of the inability of the consumer to receive a substantial benefit from the subject of the consumer transaction;

(4) Whether the supplier knew at the time the consumer transaction was entered into that there was no reasonable probability of payment of the obligation in full by the consumer;

(5) Whether the supplier required the consumer to enter into a consumer transaction on terms the supplier knew were substantially one-sided in favor of the supplier;

(6) Whether the supplier knowingly made a misleading statement of opinion on which the consumer was likely to rely to the consumer’s detriment;

(7) Whether the supplier has, without justification, refused to make a refund in cash or by check for a returned item that was purchased with cash or by check, unless the supplier had conspicuously posted in the establishment at the time of the sale a sign stating the supplier’s refund policy.

(C) This section does not apply to a consumer transaction in connection with the origination of a residential mortgage.
