My future in-laws would like to give me a piece of jewellery. They won''t specifiy a budget. All they''''ll say is "a few hundred." How do I go about picking out something? If it''s too small, that might be insulting. If it''s too big, that might be awkward. Also, DF''s grandmother has given me a cheque. Is there any polite way to combine the 2 gifts?
