I personally think an exact match is best. The represented fee is that of the server, not what the Registrar will charge the registrant (which could be above or below the registry price).
If we want to ensure that the Registrar correctly understands the price at the time of transaction, then exact match is the only mechanism to be sure of this. With our own extension for premium names we had exactly this discussion internally and ultimately opted for either an exact match or a simple 'non-standard price' acknowledgement. The reasoning being that if a Registrar specified a price, they wanted to ensure correctness and if a Registrar specified an acknowledgment they were satisfied using offline/out of band sources for price. Since discounting and mark up pricing are normal practices for Registrars, we can't presume that an incorrect value in either direction (above or below) is acceptable. My 2 cents (in AUD so therefore 1.6 cents) I originally posted this reply using a non-subscribed address, so apologies to those who've received it twice.
