Not really, its expensive if you dont bulk buy though or breed your own food, Its about 3/4 of a tub of crickets per week per adult gecko (i think havn't bought tubs for a long time not sure how many you get any more). Although i dont suggest you use a staple of just crix.
Woodies have a better nutritional value so i would recommend them over crickets also much easier to breed infact they thrive on neglect!!! but still the amount wouldnt be much different still around 7-10 per adult gecko 3-4x per week.
Mine demolish at least 25 a week, roughly 8 a night x 4 however yours are a size up from what i order although we might order them from different places.
if yours are 25 day old crickets then they are considerably smaller .These are adult spiney tails i wouldnt feed them anything smaller then 1/3 crickets.
