I brought my classic flap to SF boutique to replace the snap button, and they told me it is USD$85 and takes probably 12-16 weeks! I also asked the price of the full refurbishment. The SA told me it is $265, and said they only have 1 price increase on the repair in past 27 yrs. So seems like there is no price change on the refurbishment.
FYI, replacing a snap used to only cost $30. The $85 quote to replace a snap reflects the recent price increase.
$265 is the OLD price for full refurbishment (see old price list posted on first page of this thread). The sales associate was incorrect. If you ask for full refurbishment, they will charge more than $265. Glad you only needed one snap fixed!
