Details of the warranties are posted on wiki power supply cost, warranty described, cost

.......I’ve also attached a warranty renewal quote.  A 1 year warranty renewal is usually $.... per year, but we gave you special pricing of $.... / year if you renew both units.  This pricing is also special due to the fact that both warranties expired awhile ago.  We usually require that the warranty renewal begin on the date of expiration, but we will waive this for you this time if both are renewed.
