How to get rid of an obscenely large no. of bags for charity?

I'm not offended either.

I did ask our local Red Cross shop if they accepted donations of clothes which probably weren't suitable for sale eg old t shirts (clean) and they do because they sell to the ragman by weight.
So I label the bags
The manager also took some old duvets for the ragman. I'd normally take them to the dogs' home

I'm not offended MerylStreep. My clear outs have been annually since I retired. I follow the rule that if I haven't worn something for a year, I don't need it. Good quality stuff goes to the charity shop. Any clothes that won't be a pleasure for someone to wear, or worn clothes get recycled by one of those recycle fabric places. Towels, bedding etc go to the dogs home.

Can I respectfully request that when donating to charity shops, could people ask themselves will someone really buy this?
I ask this because I don't think some people don't realise that the charity has to pay for their skips.
I work for a very small charity where sometimes the cost of the skips can wipe out a days takings ( that's in 1 week)
I completely understand that some might be offended by what I've said but it has to be said.

I've put clothes in the Salvation Army clothes bank in my local car park-they are the only ones which I consider donating to.

I had fourteen bags picked up by the British Heart Foundation an hour ago.
It was booked online and they phoned back to make a suitable time. I had tried to phone my usual BHF shop, but they weren't answering their phone.
The men were masked and gloved and kept to social distancing.

I was embarrassed by the number of bags I had, now I don't feel so bad.

Round here the Warehouse for, I think, Cancer Research has appointments - might be worth investigating.

The charity shops and help organisations are just inundated with donations at the moment. The local shoe and textile recycling bins are overflowing too.

Is there any way that you could store the bags (perhaps in a garage) for a few months? Otherwise, try Freecycle or Ebay as they may attract people who sell at boot sales. Anything is better than sending to landfill.
