Probably an interesting pop up question before some buyer decides to commit buying a custom offer.
Just in case someone accidentally clicks accept custom offer and after 1 sec realizes he/she doesn’t agree with the order. A misclick perhaps, happens. It will save time from CS that is involved to resolve complex misunderstandings.
Personally, in order to minimize this danger, I always write a message asking buyer to read carefully my custom offer and accept if he/she agrees, otherwise we can discuss further.
