Always read between the lines of the sellers description of the item on sale. Often information relating to the condition of the item is missing, and although photographs may be provided, it is sometimes difficult to see whether there is any damage present. For example, hand painted ceramics are often described as being in good condition ( and there may be no cracks or chips), but the paintwork might be faded, flaked or oxidised. It is always advisable to ask the seller to describe the quality of the paintwork in detail. If you don't ask for details which are not present in the advertised description, the seller can come back to you with the reply - 'you should have emailed me with any queries'!
Similarly with shoes: it is always advisable to ask if there are any scuffs, scrapes or marks to the leather uppers, the rims and the heels. Often this detail is not given and they are simply described as being in 'used but good condition, with minimal wear'. Complaints after the event are often dismissed as 'subjective opinion' and returns may not be an option.
ALWAYS EMAIL THE SELLER WITH QUESTIONS ABOUT SPECIFIC ASPECTS OF QUALITY AND CONDITION.
