Dispensaries with distillate oil for cartridges? $60-75 .5 gram cart prices?

I am heading up to Boston this weekend and looking for some distillate oil to fill some carts. The pricing seems nuts for regular. 5 gram carts. I checked out veralife, resinate, and natures remedies. They are all charging like $60-75 for a half gram cart with 65- 70% THC! Does anyone have high 90%+ thc oil for a reasonable price?

I bought some back in Jan on my way to VT at NETA in Northhampton and I saw they have a store in Brookline. Are they the only ones selling it? I was trying to avoid them based off stuff I read here but I looked at so many menus and have yet to find it anywhere else.
