I tried to place an order last night, which included a new 6 month preferred customer program. Well i get an email today saying that they wont process my order because the 6 month membership is a "trial" membership. ***? I had purchased like 3-4 of these 6 month memberships in the past. They said if I wanted I could buy a year membership. I emailed them back and told them to forget the order then. I am not being coerced into buying a longer membership so they can make a few extra bucks. What crappy new service is this? Anyway, can you buy oil analysis kits for Oil analyzers from someone other than amsoil? If not I will just use someone else and stick to Exon Mobil products. What a shame amsoil, what a shame.
