Hi Karen,
There's a chance the ones you're using are "Fil-Tec" bobbins.
I have some as samples from a supplier, but haven't tried them yet. The propaganda, uhm,... sales sheet, that came with the samples said they come in L-type bobbins, in packs of 10, and class 15 in packs of 8.
Based on my cost, that retail is about right, maybe a touch high for US prices, but not astronomical.
