買い物というより仕入れですが・・・・
1）どこか仲のよい仕入先を教えてください。
Could you please introduce me to some suppliers that you get on well with?
2）つながりのある仕入れ先はありますか？
Do you have any suppliers that you are closely affiliated with?
3）御社の取引以外の商品でどのようなものがありますか？
Apart from your current line of products, what other products do you sell?
