Cheapest ever?

I just got an email from an online store saying "We miss you"
In the email it said the same plus.. Because we miss you we'll give you "free shipping". However for how long? 4 days, Dec1-4.
Isn't that the cheapest ever? I laughed the deleted the email!! If they want a customer shouldn't they give out the same thing for 1 week, AT LEAST!!

Not only being cheap, they also showed what kind of company they are!!
