I research things before i order them ,and the seller 
not very often I have a problem ,
I did a on-line home food shop the other day ,no research ,totally f**ked it up  
the bread was a tiny loaf about half the size of the one we usually have  
I've thought about that, but I just know I'd hate someone else picking my bananas and meat, etc. I like to give everything a thorough examination, give bread the pensioner squeeze (If you look on the top shelf, all the bread has been squashed in the middle and rejected)  
I did it because sainsburys sent me a £20 off voucher as a first online shop,
they delivered exactly what I ordered 
I don't need to order fruit or salad or veg  
 
 
they even deliver booze n fags  

you could probably get a sainsburys £20 voucher off interweb ,minimum spend was £60 IIRC
just order tins etc if you want to squeeze buns when you shop  

you do have to pay about £3 delivery for a 1 hour time slot 
and read and check the weight of things (loaf weight  

 , tin size for example )
