I just checked my slings & my chilensis which I brought at the Bedford show last year have a FatBob Exotic's label on them & he has some listed at 25 Euro.
The only issue may be getting them posted at the moment.
Edited to add, these are REALLY slow growers, I have had mine since the Bedford show in September & they are still 0.5 cm's. Hence, why the label is still on the vile I brought them in.
I have contacted exotic Bob he doesn't have any more in stock but thanks
