I donated non-cash contributions to 3 different charities. I donated on 8 different days. Each days donation was under $250. All 8 days contributions totaled a little over $1000. I have receipts for most of these donations (except the places where there was no attendant to give receipt. The receipts I did get are from goodwill that acknowledge how many pieces or how many boxes they received from me. I have an itemized list of what was in each box and I valued it all at thrift shop values.
