Christmas decor is not 50k to get in and never has been. I think someone may have added a 0 to the actual cost.
We use smart shopper which is a competitor of clipper, but he gives me great prices. Good for getting the name out there, but you will get tire kickers.
I have not looked into the postcard option, I am thinking about doing the saturation mailer the post office is doing and just picking routes. probably cut down on the total cards I send out by 50%.
