USA credit(!) cards, and fucking 250 or 300 usd limits during online shopping...

[fordlaser]

Hi guys,
recently I am struggling with these fucking limits (limits or something diferrent ???)
, the things are:
I can not recently buy something with the price over 250 or maaaaaax 300 usd,
wtf ???
Credit(!) cards: fresh, virgins, from BARCLAYS BANK DELAWARE usa, card levels: world, signature.
I need to be able to buy items for minimum 500-600 usd in one transaction(s).
But recently I bought only shit items for 150-200 usd max.
In this bank they have some default limits 200-300 usd as default for online shopping ???
Have anyone know good usa banks with higher limits or no limits for online shopping ?
I am not asking for BINs, I will find it by myself.
Asking for good usa banks .

Please write here all your thoughts , opinion and advise.
Thank you.
