I mean if I would do it with an item around 800 euros easily rather than multiple items or a single one around 2k euros, I‘d prefer to do it and repeat it with a similar value about a month later.

Low to mid value Items are less likely to attract attention, as opposed to those of high value.

Could you please give me numbers for these areas?

Generally speaking:

Low value: < 350$
Mid value: 350$-750/800$
High value: > 800/850$
