Should I wait for herrschners for schipper

I really want to get this specifit kit and I live in NY US

I have been ordering through herrschners but they have limited stock

and only place I could find this specific kit is through amazon

price itself is hugh but shipping is also like $40..

Should I wait for herrschners to update their stock

I only started recently with schippers pbn and I really love them but $183 in total for 1 kit is insane price
