I once bought a new, in box, pair of gold seals for $10 on ebay as a buy it now auction - shipping was $14, making a total of $24
I "sold" them to my coach for exactly what I paid, and she passed them on to one of her skaters.
I also recently bought my daughter an 8 1/2" pair of pink matrix legacy blades for $30.50 including shipping - as far as I can tell they have only ever been sharpened once, and show less wear than the ones pictured above (in terms of scratches/nicks - there are some, but not many). I haven't put them on her skates yet (they're sort of her "carrot" to get past basic 8 - she gets them when she graduates to FS1)
The Legacy is roughly equivalent to the coronation ace and professional blades, which are honestly one of the few freestyle blades that are truly suited for "all levels" of skating - my daughter had been skating on coronation ace's since basic 5 (prior to that she had MK Double Stars). My daughter has wanted colored blades since I got my first pair about 4 years ago
