lazy or cheap?

Having nursed 6 children for an average of 14 months I have spent much time wearing nursing bras and tanks. I really like Target's selection that allows me to keep my tummy covered while breastfeeding. However, the plastic snaps and strap adjusters have broken on several, leaving me to keep them together with safety pins. Since Julia Ellen is almost 12 months old, I really can't justify the $50 expense and hassle of shopping for new nursing gear since she likely will be weaned in the next few months. Perhaps if the last intact one breaks in the next few weeks I'll give in, but I'm hoping I can hold out until she learns to drink cow's milk and then throw the whole pile out in the trash.
