$250 limit for charitable contributions with no receipt

I'm doing itemized deduction this year and have some questions about the no receipt limit for charitable contributions.

 

We regularly contribute $15 per month to three different organizations. For each organization, our annual contribution is under the $250 limit for donations without a receipt. However, when combined, the total exceeds $250. We do have bank statements showing those transactions.

 

Can we still claim these contributions without receipts since each individual organization's donation is under the $250 limit? Getting receipt is a hassle and takes forever 🙂
