Water pump upper o-ring seepage - how much time do I have? 700 1991

Have found some seepage from the mushroom-shaped o-ring between the top of the water pump and the head. Very little, maybe two to three drops per day. Do you guys think I have enough time to order a new pump from Tasca Volvo (genuine Volvo for about $63 + shipping). It should arrive here by next Friday. Or do you think I should get one from the local Volvo dealer (probably over $110 + tax), and have it by this Wednesday and install it the same day.

And, yes, I do need to change the pump: the shaft seal is seeping from the lower weep hole - long story.

The car is used every day, about 65 to 70 miles per day. I check on it every night. It has run this way since last Thursday with no apparent increase in seepage rate.

Do those big o-rings fail suddenly and catastrophically, or will it just seep for a little while until I can get the new pump in?
