The fundraising page for the mother and daughter had raised more than $450,000 from a goal of $750,000 as of Saturday.
On GiveForward.com, a dedicated Boston Support Page let users choose between supporting 13 families affected by the bombing. Collectively they have currently raised $719,957.
The sites also have staff members that watch the fundraisers and contact users to ensure the websites are not used to support scams. According to Nate St. Pierre, the director of communications at GiveForward.com, the website has cancelled about 20 attempted fundraisers.
Both websites deduct money from transactions, the website GoFundMe.com deducts 5 percent from every donation and GiveForward.com deducts 7 percent from every transaction.
