We recently took in a Jersery Fix that was framed by an online company. The frame was broken in shipping, the glass us non uv plexi and there was so much tape - the wrong kind of tape, we were shocked. Hands down the worst we have ever seen. The Jersey was held in place by brads that created large unnecessary holes in the signed jersey. The color of the mats were not even the tem colors. Needless to say he paid us as much to fix it and make it right as he paid the online place.
The products used are very important, even the ones you don't see. Please always find a local small business frame shop to frame things for you. The minor savings you might get online is not worth ruining your art.
