4 TVs to upgrade with 2 coupons


My family has 4 TVs to upgrade by February. I've broken down the costs like this:

4 Converter Boxes = $200
2 $40 Coupons = ($80)

Total so far = $120

3 Antennas = $80

Grand Total = $200

This is much too much for us to spend, especially with Christmas around the corner. Is there anyway to cut costs on this? Only 1 of our TVs has a set of rabbit ears, all the rest of them are connected by Tin Foil which works just fine, but from everything I read, we have to have a antenna with each TV.
